There's a core of a good game here! I really like the vertical level design, and the concept of having to touch the two sides of the screen while finding coins is a great and funny take on it.
There's two major problems though, the first being the background. Since it doesn't scroll with the screen, it really, really hurts my eyes when everything else moves and it doesn't. That's pretty much the only thing preventing me from playing any further.
Secondly, the timer for melting needed to be a lot more obvious, I was fairly confused as to why I reset a few times despite reading the description.
Despite the flaws, though, the game was still good, and I'd love to see a more polished version in the future! I'd happily play more of it if just the background were fixed!
