I realize now some people don't have the patience to beat 1p story mode. So I'm posting the codes to unlock the extra modes. Perhaps it won't be as repetitive now.
Wow, front page? Awesome. Can't thank you guys enough. And I'm uber-sorry that the stupid high-score-thing doesn't work on Newgrounds. If you're hard-core about it, it works on my site. Otherwise, thank you for enjoying my game anyway!
My original game Pengu, revamped and packed with new features. Still no pause feature, and a glitch here and there, so sorry.
A BIG thanks to Synj for supplying the awesome artwork, and Tom for... doing stuff.
