On Tigersource forums, Aaron Steed (under the username st33d) said something about a secret level editor. It seems that Jay is Games gave away the code, so now everybody can acess the level editor. How do you access it? Well you press ↑, ↑, ↓, ↓, ←, →, ←, →, B, A, then click play. (the ↑, ↓, ←, → are Arrow keys). I found this so cool when I first used it.
