Developer Notes

You can also access H-scenes by recruiting monster girls and maxing their affection. This is our first ever game, and we’re a bit nervous to post it here. There are still a lot of unfinished and unpolished areas of the game, including bugs. Please consider supporting us if you enjoy the game and want to help it grow bigger.

Installation Instructions

Extract, and run the game.
