I think you shouldn't have the HUD made up of 2D resized images. They look all crappy that way. I think you should apply them to 3D polygons that are locked to the screen and have Z-depth off, so that they stay on the screen. I don't really like that way DBPro does 2D graphics, and I've had ideas on how to use 3D planes to make for much better looking 2D graphics.

Also, I'd like to say that you should turn off the stupid screen resizing thing and make it so it actually changes resolutions. I've seen too many DBPro games that don't actually change the monitor's resolution but just resample the game screen to fit. It lowers FPS and it's kind of pointless (It also seems to interfere with hardware-accelerated Anti-Aliasing).

After you jump, you should make it so you have to press jump again before doing the special jump. Make the jumps variable jumps, and make Jazz's helicopter move last as long as you tap the jump key. Otherwise Jazz is ultimately inferior to Spaz.
