About This Game

☆Futanari x Enhanced Tentacles!☆

This is a Futanari type piece!
Please note: HCG consists entirely of Futanari and Tentacles, there are no H-scenes with humans!
The protagonist will always wear a straitjacket and will not be able to take it off during the H-scene.
☆Gameplay Description☆

There are two types of battles:
Attack Mode, where you fight directly on the map, and Turn-Based Combat, where you use commands and choices.
It's a mix of different combat modes!


☆Boss Battle H is fully voiced!☆

There will be a lot of voice dialogue during the battle!
CV：大山チロル様

There are two main types of H-scene: the dubbed H-scene after losing a battle, and the H-scene where you get caught in a tentacle after making contact with a monster on the map.

There are three difficulty levels to choose from:
☆Estimated playing time☆
Easy: 1 hour (Just go ahead and clear the area.)
Normal: 2 hours (It requires both upgrades and money, and is recommended for players who want to experience simple combat failure)
Hard: 5 hours (The enemies are very tough, so we recommend beginners do not choose this difficulty, but try the challenge after the first game!)
※H-events mainly occur when you lose a battle, so if you choose to play in easy mode at the start, you may not see the HCG!


☆HCG Playback room function☆

The HCG replay will open after the game has finished!

Spawn planting, spawn laying, etc.
There is also anal sex!
はく汰 sensei's plump, fleshy characters and the awesome tentacles designed by 土ノ下かえる sensei are also big draws!
☆The story☆

It's a time when a faster-than-light substance has been discovered and humanity has migrated to Mars.
Suddenly, one day, an organisation lost contact with the centre.
They also found many unidentified life forms and tentacles wandering around the roadside.
Newcomer "Sasha" is a member of the Masta Zones (like a cosmic police force).
With the help of "Nabiko", she goes alone to the organisation to investigate...
