(double-posting for more attention)

I've just removed a level (where you mostly progress using airscrews/ upwinds) because it wasn't fun, so I'm in need for a new one (or two, if you have good ideas). It has to be indoors and should not contain ice/ snow and little to no lava.
If you have an idea or know a nice level from any side-scrolling game, I ask you nicely to share it with me!
