Thanks for posting this :) To answer some questions about the update:
Yes projectiles are a little more slow, not because they render slower though, because the animation speed was slowed down so you can more easily see the awesome effects :) You can change the update speed of the game now in the settings.

Also a comment about Acky's XP Breakout, I am working on the WM5/VGA update for it right now, it will support all devices, square screens, and much more. I noticed Menneisyys really hits on music in his reviews, the music in Acky's XP Breakout was done by true 'scene' artists and one of the tracks was actually voted the best trance track in 2003 in Netherlands I believe, or something along those lines.
If you havn't checked out Atomic Battle Dragons, my latest game, the music in it is the best yet I think, I worked really closely with the musician and came up with some tracks that really support the game and theme well.
