Void Prisoner

Monsters come from nothing, and to nothing they return. You are a slave. You will spend an eternity following instructions. Create. Destroy. Net gain: zero. Listen to your lord. And don't disappoint.

Move with the left mouse button. Pick up items with a left click, and drop items with a right click. Combine orbs to summon a variety of different creatures, and throw the creatures back into the void to get your orbs back.
