Pretty cool 3D effects. I really like that there are upgrades, and that you shared the source for such an awesome game. I can't wait to get home to take a look at that. Only gripe about the game is that the cursor dissapears when hovering over enemies, makes tracking somewhat difficult....also, upgrades are a bit too pricey....and the game seems to hang a bit when shooting. At least for me it does.
out of 10...
gfx - 8.5 (killer 3D, but could have used more color)
sfx - 8 (good song, solid sfx)
design - 8 (needs cheaper upgrades)
gameplay - 7.0 (fun to play, but cursor has issues)
overall, this is some very impressive 3D that works well for this type of game. Presentation lacked color, which made me feel sort of like I was playing a game made of newspaper. Love that you shared the source code, can't wait to see how much of the 3D is actually rendered herein.
