Nice idea for a game! The difficulty didn't really have a curve, as the second level to me felt like the hardest out of the ones I played. Is the green boogie man's movement randomized or is there some kind of pattern to it?

The mac export doesn't seem quite right. I expected a .dmg file.

I liked the conga line of ghosts following me around. The volume of the music is really low, I can only really hear it well when I set my volume to 100. Some of the levels were interesting to play, but with only 2 monster types the game feels repetitive. Would have liked the controls to be shown somewhere, but they were easy to understand for me.
