This isn't really the place to ask about that as it's not specifically related to NeoLemmix (indeed, it's even possible there may be some contests where NeoLemmix levels aren't accepted; the rules vary from contest to contest); questions relating to contests should be on the contests board. But to answer your question, I don't plan to run official contests with more than two prizes at the moment - indeed, due to the low number of entries, I may even reduce it to prizes for first place only in the future (but we'll see). However, other users are more than welcome to run contests of their own (whether just-for-fun or involving prizes) on the contests board, so if you'd like to do one - and you're sure you have the patience to stick around and see it through - you could do so. I must say though, that sounds a bit overly complicated. The official contests stick to a single theme, rather than awarding various types of levels.
