Gameplay
Combat involves your character tearing another Cubivore apart once its health has reached a low enough level. You can perform many different actions, and while tearing limbs seems violent for an E rated video game, its done so in a lighthearted manor. Limbs can be consumed by your Cubivore, which will cause it to gain a bit of health. Bosses have special limbs that, when absorbed, will give the player new powers.
