Could have been improved
You should have used the graphics that someone suggested and posted for you (for free!) on the Mochi community forums. It really would have improved this game more.
Also, this froze up at Level 6 for me - I couldn't get past. I hope I'm the only one with this problem. But I'm voting 5 to show my support, I know that homemade games do that sort of thing all the time. I wish you the best with your game development and hope everything works out for you.
By the way, how did you get a sponsorship for this? My game, Keyboard Defender, spent weeks on the FGL with no replies, and I remember you saying that you got yours in three days...
