Really good game! The idea is so cool and the game built around it is very well done. I like a lot the artwork and maybe music would be a great addition.
Currently the player gets stuck in walls and can also just rush all the way to the bossfight without having to deal with enemies. Maybe only being able to leave a room when all enemies have died would be a good way to control that.
Still, really good entry, I enjoyed a lot playing your game. Good job, keep it up!
Also would highly appreciate if you could checck out and rate my game, thanks :)
