Solid puzzle game with creative mechanics. I liked that screen transition effect, it makes the game feel polished.
I was about to comment that it would be nice to see everything in one screen... until I realized that I could zoom in/out by mouse wheel. That's a really cool feature, though it could be communicated better in-game.
I wish I could see how many moves are left before overheat in numbers, it can make the game more predictable to play I think. Nice game!
