Slimegeon is a 3D first person roguelike dungeon-crawler game where the player runs through dungeons and possesses defeated enemies to use their abilities and takedown bosses to continue to the next floor. Through the dungeon, the player can level up the unique skill trees for each enemy. The player can also find items that will assist them on their journey. The goal is to take over more and more powerful enemies and stay in your weaker slime form as little as possible.
