HatLand

Every run is put together differently: the rooms and what's in them change, and bosses are waiting — a giant worm, a tank, a lava beast, a lord of clones, and the King himself.

Shoot with one hand and move with the other — you can aim and run in two different directions at once. Build up mana and spend it: a hammer, a volley in every direction, a clone of yourself, a rolling wheel, mines, or three seconds you cannot be hurt in.

Collect resources to upgrade at the machines between fights, and don't be in a hurry to die — you get a second chance from the very start.
