I guess I should thank you for your support. I don't know how other people have gotten so many stars, while I have much fewer. Oh well, maybe I can think of another good idea sometime.
Fun fact: The latest level I made was delayed in development, when the new stage elements (esp. Fire Clown Car) came out, I used some of those to give the level more options.
Apparently, the Bob-omb challenge isn't as difficult as I said it was.
