Great game!
However, it needs some UI improvements:
The ability to speed up the game (a 2x button) would be very nice. The fact the game freezes when it is not the active window makes it way too slow.
It really needs a menu interface.
An end game message is needed. I beat Pearly Gates twice wondering why it didn't advance. Is that the last level?
