Awesome game! I have just one problem with it...
There are too many "lava run" levels. You know, the ones where you have to move up before the lava gets you?
I know you hear this a lot, but take a page from Super Meat Boy or even Newgrounds' Deadly Dungeons, having one "lava run" per section. Otherwise its just gets redundant and annoying.
Otherwise, awesome game!
PS. (I don't know where to get the last secret trophy D:)
