Polymobea is a short, sweet and calming survival game. Take control of Poly, a little polywog-amoeba thing trapped in a purgatory space-like state. Collect items. Lose items. Fight bosses and enemies. Allow the atmosphere and noise to calm you for a moment. Aim to ascend.

What is Poly?

What is anything?
Those are questions you'll have to come up with answers to yourself. Interpret it as you will. Make it your own.
