Hmm
It's not a good game, but not a bad game, either. Some instructions would have been nice (so that one could read what different powerups/powerdowns there are and what color the have, and so on).
Also, some backroundmusic would have been nice, too.
Umm, it was original.
It was very bare, but that's not a bad thing, it made it feel very retro-y. It was quite different from most arcade games I've played, though.
Just not much fun
I'm not really sure what the point of this game is. It could use some background music and some instructions.
