The movement is a bit busted. But I like the theme and the concept. Remarkable artwork too. Hope you release a updated version with improvements :] Nice work
just pointing out a little bug : If you die and respawn, and go to the place where you do the first switch to the "s key" other world, you won't get the charge to switch .
A little tweak to the gravity and mate, and that is a solid game you got there. I suggest you don't drop this one and add maybe like more enemies and weapons
