Story
After the events of Succubus in Wonderland, Reto attempts to use the transfer stone on the roof of Wonder Castle to return to his world again. However, the transfer fails due to a lack of magical power, so Reto has to wait three days for the transfer stone to regain enough power.

During these three days, Reto can explore the castle and interact with its inhabitants. Depending on the player's actions, he can talk with the various inhabitants of the castle, be hugged by some of them, engage in sexual activities with them, join in meals, wash himself in the bath, and encounter a strange succubus from another world. During the second day, it's possible for him to eavesdrop on a conversation between Carroll and her mother, in which the former admits to taking power from the monument so that the transfer would fail and Reto would stay for longer in this world.

At 9 pm of the third day, it becomes possible for Reto to return, and events diverge:

In Normal End A: Being Dense, Reto and the others head to the roof. Carroll is slightly angry at Reto being too dense to realize her feelings for him. She orders him to learn how to understand a woman's heart before he returns. She also gives him a kiss just before he leaves.
In Normal End B: Promise with Carroll, Reto and the others head to the roof. Carroll says that these three days have been fun, and asks Reto to stay faithful to her and promise he will return. Reto leaves.
In the True End, Carroll interrupts Reto before he can head to the roof, and brings him to her room. She confesses her sabotage of the transfer stone, but Reto forgives her for this. Grateful, she lovingly has sex with him. Then she and the others see him off as he returns to his world.
There are also five different Bad Ends. Getting any of these ends the game immediately, regardless of remaining time.

In Bad End 1 ~Failed to Escape the Succubus~, Reto attempts to sneak out of the castle at night, but the Gatekeeper Succubus wakes up and rapes him, making him her sex slave.
In Bad End 2 ~Punished with a Sudden Fall~, Reto draws on a portrait of the Queen with the Diamond Marker Pen, causing the floor to open under his feet and drop him into the abyss.
In Bad End 3 ~Hero Soaked in Milk~, Reto enters the bath while the card soldiers are bathing and is raped by them, and decides to stay in the castle.
In Bad End 4 ~The Princesses' Younger Brother~, Reto agrees to be adopted by the Queen of Hearts, becoming her new son and the new brother of the princesses.
In Bad End 5 ~Just did it with a scarecrow~, Reto feels horny while looking at the scarecrow in Castle Gate and ejaculates on it. He is witnessed by a disgusted Carroll. Rumors of his action spread through the castle and even seem to follow him when he returns to his world.
Gameplay
The gameplay of Carroll in Wonderland is quite different from that of most other games:

There are no battles and, by extension, no experience system or equipment.
There is an in-game clock and date, represented by an analog clock in the top right corner of the screen and the words "Day X" next to it. Time advances depending on the player's actions, and the player returns to their world on 9 pm of the third day.
Conversation and giving presents are important parts of the game. In particular, this is necessary to raise Carroll's opinion of Reto, which affects the ending.
There is a score system, with the player getting a score based on their performance once they complete the game.
The game takes place in a relatively small set of areas, primarily Wonder Castle.

Time
The game takes place over three days. Each day is split into morning (7.00 to 11.59), afternoon (12.00 to 21.59) and night (22.00 to 6.59).

The card soldiers rotate their shifts based on the time period: Clubs Soldier is on guard duty in the morning of the first day, Diamonds Soldier in the afternoon, Spades Soldier at night, and Hearts Soldier in the morning of the second day. The card soldiers are in the Entrance when on duty, and in other places otherwise.
There are meals in the Great Hall each day: breakfast is 8:00-9:00, lunch is 12:00-13:00 and dinner is 19:00-20:00. The player can join in a meal at any time between its start and end times.
Lewis is cooking in the Kitchen prior to each meal.
On Day 1, Carroll is initially in her room for a few hours, then moves to the Warehouse for a few hours to talk to succubi there (during which the player can't enter the Warehouse).
The Communal Bath can be entered at any time, but Reto can only wash himself during the period 20:00-22:59. At other times, the Communal Bath is unusable or has other succubi using it (which may lead to a H-scene).
Unlocking all scenes
It is possible to unlock all H-scenes in the Recollection Room by two methods: obtaining the True End, or changing Reto's name to "ＥＸかいでん" using the yellow crystal in the Recollection Room. The latter method will continue to work even if the player subsequently changes to a different name.

True End
Two conditions must be satisfied for the player to obtain the True End:

The player must ask each of the card soldiers at least once about what they think of Carroll
Carroll's affection must be 25 or more
Carroll's Affection
Carroll's affection can be influenced by the player's action, and it affects the ending they obtain and their final score. Certain actions are highly effective at increasing it:

Giving Carroll the Egg Sandwich during Day 1
Eavesdropping on Carroll's conversation with her mother while Nekomata is in the hall during Day 2
Choosing the option "Fluffy omelette" during the dinner of Day 3 (this option only appears if the player has been attending previous meals, necessary for Carroll to cook the fluffy omelette on Day 3)
Any two of these actions will result in enough affection to satisfy the second condition of the True End.

If Carroll's affection is below a certain threshold, then her dialogue has some changes and her affection will increase by 1 point whenever you talk to her.

Carroll's affection can be decreased by:

Entering Carroll's Room during the first few hours of Day 1 and then leaving without talking to Carroll (-2 points).
Obtaining the book "100 Methods to be More Honest" from a bookshelf in Carroll's Room (this is available until 14:00 of Day 2), and then talking to Carroll (-3 to -8 points). If the player has picked up this book, they can put it back by examining the bookshelf again.
Hugging a character other than Carroll.
Giving a present that is not involved in progressing events.
Presents
The player can give several characters presents, for a variety of outcomes. Notable ones are:

The Diamond Marker Pen can be given to Diamonds Soldier, and causes her to give you the Spicy Fried Chicken in return.
The Egg Sandwich can be given to Carroll for a major increase in her affection.
The Spicy Fried Chicken can be given to Lewis, and causes her to give you the Teddy Bear in return
The Teddy Bear can be given to Carroll for an increase in her affection.
The Heart Handkerchief can be given to Hearts Soldier, and causes her to give you the Succubus Liquor in return
The Succubus Liquor can be given to Carroll to trigger a H-scene in which she is drunk
The Old Hat can be given to Hatter, and causes her to give you the Small Key in return
The Dinah Medal can be given to Alice, and causes her to give you the Beautiful Box in return
The Fish Keychain can be given to Nekomata, and causes her to give you the Hardwood in return
The Hardwood can be given to Spades Soldier to complete her sidequest
The Love Brooch can be given to Carroll for the highest possible increase in her affection
Egg Sandwich
To make the Egg Sandwich item, the player needs its three ingredients:

Bread is obtained from a succubus next to the crate in the Kitchen, from 13:00 to 16:59 of Day 1.
Mayonnaise is obtained from a pot in the southeast corner of Konoe Waiting Area 2
Egg is obtained by giving Chicken Food to the chicken in Castle Gate. Chicken Food is obtained in Konoe Waiting Area 1
With these three ingredients, the player can make the sandwich by examining a bench in the Kitchen.

Love Brooch
The Love Brooch is the most difficult item to obtain. Missing any of the steps (most of which are time-sensitive) in the process will prevent the player from obtaining it.

The player must first talk to White Rabbit in the Library during the morning of Day 1 to obtain the Dinah Medal
They must then give the Dinah Medal to Alice when she appears in Castle Gate during 20:00-21:59 of Day 1
They must also talk with Lilith (this can be done before or after giving the Dinah Medal to Alice), after which they will obtain the Old Hat
During Day 2, they must give the Old Hat to Hatter in Castle Gate to obtain the Beautiful Box
Finally, they must examine the Beautiful Box in their inventory to open it and obtain the Love Brooch
Eavesdropping
To eavesdrop on Carroll's conversation with the Queen of Hearts, one must first talk to Nekomata in Castle Gate from 10:00 to 13:59 of Day 2, then go to the Main Hall during 14:00 to 14:59 of the same day. The NPC that normally blocks the entrance to the Queen's room will be blocked, allowing you to go to the entrance and examine it. Choose to eavesdrop.

Meeting Lilith
A door appears in Castle Gate (to the west of the actual castle entrance) during the night of Day 1. This leads to a strange space containing the secret character Lilith. After this sequence is over, the player will be sent back to Castle Gate, the door will no longer be present, and the player will obtain the Old Hat item.

Bad Ends
There are several Bad Ends to the game. Reaching one of these will immediately end the game, regardless of the time, and greatly reduce the player's score.

Examining the scarecrow in Castle Gate will give the option of masturbating to it. This will be seen by Carroll, disgusting her.
At night, the Gatekeeper Succubus is asleep and examining her gives the option of trying to sneak past her. Doing so causes her to wake up, rape Reto and make him hers.
Examining the portrait in Entrance while possessing the Diamond Marker Pen will give the option of drawing on it. This causes a trapdoor to open underneath Reto.
Interacting with the Queen of Hearts may eventually lead to the option of becoming her adopted son. Accepting has her remake Reto into this.
Entering the bathhouse during the afternoon of Day 3 causes the player to run into the card soldiers bathing, and they proceed to gang-rape Reto.
Score Calculation
The player obtains a score for completing the game, though this does not have any important effects. This score is determined by the following factors:

+300 points for each point of Carroll's affection
+1000 points for each Proof item, obtained by solving the card soldiers' problems
+1000 points for giving Carroll the Egg Sandwich on the first day
