@Hercules - Great Ideas. Yes, I realize the game is very early, but I uploaded to get ideas from the Kong community. Thanks!
@Comrade - A shadow background? Can you elaborate more?
@ikarashin - The 'submit score' only pops up once you beat your current top score. It should not popup unless you are consistently getting a better score, which is a good thing.
Crazy pixelated effect! Very unique idea and pulled off well. For the sequel, maybe you can add power ups that decrease the effect. Or, have it so that if you don't kill enemies, the effect gets worse and worse. A lot of concepts to be explored here.
