I think it's great that you took the time to create multiple mini-games. I couldn't finish it because of a bug: when I was two kills away from winning level 2 when food collisions stopped working, I couldn't die but I couldn't hit ennemies either.
If you want to try other level, there is a cheat code, on main menu you can press "I" to skip to level 2 / "O" to skip to level 3 / "P" to give 999 lifes.
