Nice. It was fun to explore.

I found sometimes the character would move to the next screen but the camera wouldn't follow so I was stuck looking at an empty room! This twice happened after I'd gone into a new room and seen spikes right in front of me so I quickly backed-off but then accidentally went back into the first room, so I went straight back into the spikes room the camera wouldn't follow. Maybe it's something to do with two room transitions in quick succession.

Having the projectile speed a lot higher from the outset would be good.

THIS IS BINDING OF ISAAC CLONE!!1!11!1!1! Sweet game, cool beans. Thought the projectile was a bit slow and it's limited range was annoying at times.

You made a procedural dungeon. Cool! But some of the rooms double up on each other.
