MidBoss is a video game about possessing your defeated enemies in order to become stronger. You play the weakest of the dungeon denizens, an imp with no ability other than possessing other creatures. Your goal is to defeat and possess increasingly stronger creatures, unlocking their abilities for yourself and becoming stronger as you go along, and eventually defeat and become the dungeon's ultimate endboss.

Buy MidBoss now and you will get a Steam key as well.
