Thanks! I think it might be a PNG gamma issue. It might be messing up the image that tells the game where the door is. Unfortunately I can't patch it while the games are being judged, so maybe try with a different browser?
Oh, yeah – door’s in the right place, but it’s not triggering when I touch it in Firefox. I don’t get the ‘more coins’ text that I see in Chrome either.
Now that I’ve played a few more levels, I like the shape-changing mechanic as well. Gravity seems a bit strong.
