Wow what great music!
But even with that great music, after suffering through levels, I had had enough. Cute, simple idea (walk over all the question mark blocks, which give you power-ups too, of course avoid enemies), but I hate when games have that glitch/feature where you get stuck up against walls. And tho I worked around that for the first 2 levels, it just wasn't giving enough to push through the quirks it had like that.
