Went through the trouble of getting it to work, only to find it's still pretty rough. I wanted to like it, it's clear that lots of effort went into it from the graphics, but I couldn't do anything and just died repeatedly a couple of seconds after starting, even if the enemies didn't get to me. I guess you're supposed to protect something in the level, but it's over so fast that you can't really tell what you're supposed to do. None of the colour buttons seemed to do anything when clicked either.
