Cool game ! The visuals looks really neat !
The game could really use some music & sfx to complement it.
The room felt a bit small compared to the player size, making the dodging part of the gameplay a bit tight. Also, the random generation of room could use some balancing you sometime start with a very hard first room (you should consider starting with easier room and ramping up the difficulty as you clear rooms)
appart from that, very cool entry. good job :)
