I can think of a solution or two that should work. If they don't - or nobody else comes up with another one - then I'll apologize. I just figured we'd have enough of catapults and wanted something else - because that level was still easily beaten by catapults.
Sorry if I've offended anyone
edit: Yes, this wasn't all too hard to beat, in fact the solution I was hoping the level would work for worked... and I made the level both harder and easier (no hole in the ground and more space to work with backwards). Also, if you edit the level but doesn't make the way you solved it harder to do, it'd just mean people can try the same solution over and over again.
