Fun game, in theory. However, I've got a big problem with how incredibly unfair the randomness can be. There is quite literally a chance of losing all your lives without leaving the first room because of those spike rooms. Combat itself is buggy, usually with enemies preventing the player from moving or dealing too much/not enough damage due to the collision system. Maybe add a bit of air control, remove the insta-death rooms, and fix up the combat and this is a solid game!
