It was a nice,balanced, hard game- and then I matched my first gem, and won trivially. I would get rid of money entirely, maybe just a move counter, and also the gems.
Excellent game, with a great moral! The only issue I had was that some bits (level 4 partiuclarly, because the cloud didn't have the bounding box where I expected) were kinda precise. As a suggestion, if you make the characters like half as big in each dimension, and keep the boxes the same size, it might make some of those better
And for all those folks telling you to focus on the graphics: The graphics are what make people buy the game, but the heart of the game is in the mechanics. If you want to make the graphics, yea, sure, it will make the game more appealing, but it won't make the game better- just easier to sell.
Very nice! It would have been good if there were any choices to be made on like the last 2 or so levels, to really pump up the difficulty, but presumably thats in the full game. Very nice!
