Udonge in Interspecies Cave is a 2D pixel platformer where you play as a sexy purple-haired bunny girl named Udonge who tries to navigate her way out of a tentacle-infested cave full of monsters seeking to have their way with her.

Story

Udonge follows a purple-haired bunny girl who, without warning, is pulled into a strange pit that suddenly opens beneath her feet. She ends up in a dark, unsettling cave filled with eerie, tentacle-like monsters and pleasures beyond this world. Determined to escape, she sets off to find an exit out of this nightmare.

Gameplay

The game features three brief levels to navigate, each concluding with a distinct boss battle. Across all stages, players face a total of 8 monsters. The entire game can be completed in under an hour, fitting within the Steam store’s 2-hour return policy. This is intended to signal that the experience is a short one with very little content to engage with.

Hentai Content

Udonge’s health is shown on the left side of the screen, reflecting both her physical condition and her emotional state — pleasure or disgust — as she confronts the cave’s monsters. When her health depletes to zero, she becomes vulnerable to sexual attacks, initiating an H-animation as she collapses in place. If she can’t escape the enemy’s grip, she is overcome by her injuries, transforming into a sex toy for the monster to use. This results in a game-over screen.

After completing all three stages, a gallery section is unlocked from the stage selection screen by moving to the left. Here, you can view every H-animation, including those not encountered during gameplay. Each H-animation can be zoomed for closer inspection or switched between different variations. They loop infinitely for continuous viewing.

The gallery features 8 enemy-related H-animations and 13 game-over H-animations.
