About This Game
You were swallowed by the tentacled creature... but instead of becoming another victim YOU TOOK CONTROL!

Now the eldritch mass obeys you. Your body is still lost somewhere in the depths, but with the help of your brilliant (and curiously eager) elf researcher girlfriend, you might just claw your way back to freedom.

Core Gameplay
Click to harvest neurons and grow your tentacle dominion

Upgrade tentacles with roguelite-inspired card choices

Face walls that force prestiges ("Attempt to Escape") to reset and gain tokens for unlocking new scenes!

Evolve mechanics with run-meta cards: crits that spawn Hearts, rerolls, and more!


Every run is a bit different. Pick from 3 (or 4) upgrade cards each level - classic upgrades clash with opportunity costs.

The Erotic Twist - Your elf companion isn't just helping out of kindness. She's fascinated by your new abilities... and wants to study them up close. Progress unlocks her increasingly intimate "research" sessions, heart-pounding encounters, and tentacle-driven fantasies. "It's still you in there, so it's not cheating, right?"

Collect Hearts and Brains and access the Gallery - a collection of animated scenes. Each entry costs more than the last, but you choose the unlock order. Packs form mini narrative arcs.


Features
Semi-roguelite progression with run-permanent meta unlocks

Narrative woven through intro, a few prestige milestones, gallery unlocks, and ending

Inverse scaling: faster Hearts at higher levels, but harder to gain new levels - do you prestige or count on your luck for a rare card that gives extra Brain token?

Try to escape until the Gallery is complete and have your happy ever after!

... Or just unlock the entire gallery to view scenes with a cheat code and don't bother with clicking.

Adult content focused on tentacle themes, power dynamics, consensual exploration, and body-altering pleasure

Roughly 3-4 hours of playtime, maybe more, maybe less, depending on your luck and strategy


Can you escape and reclaim your humanity? Or will the tentacles claim you forever?

Tentacle Master is a blend of idle clicking, roguelite choices, and erotic storytelling. Perfect for fans of cozy incremental games with a mature, narrative-driven edge.
