More issues:

I can't fullscreen it.

The spin jump doesn't work very well. It seem to require a particular length of run-up, rather than just pressing jump while moving horizontally. Also, when you do a regular jump, you can't turn around in mid-air.

The controls aren't told to the player. They're not unintuitive, but I still think you should put them in a readme file or something. If you can, I think a better way to do it would be making them remappable.

The super bombs propel you at INSANE speeds if you're moving at the moment they explode. This "super-knockback" doesn't even end when you hit a wall, it seems to stop when it feels like it. The super missiles have the same issue, probably due to code reuse.

There's a vertical strip of rooms on the left of the map that doesn't show up. More precisely, they get marked on the map, but disappear the next time the game is opened.
