It's good
I like the idea. My only problem is with the puzzle-graphics. The various "units" (puzzle elements) are too big and pixelated, and they really mash together when you look at it. They could have been a bit more subtle and easier to seperate with the eye.
Otherwise it's a pretty good timekiller
Addicting
Even though the game wasn´t perfect, it was very hard to stop playing. I had some trouble seeing the difference between the characters when matching them, especially when they´re not upgraded. I had absolutely no use of the stuff you could by, so my tip is to put all money in upgrading the characters.
I never had time to see the animations, but my 4-year old boy enjoyed it and gave me time to play.

No new Game button, that sucks
interesting...
not my kind of game, but not a bad idea.
Too easy...
I thought that every level was too easy, almost a bit boring, even the level that most people complain about wasn't that challenging. The items were useless, they really weren't worth the money.
I wish I could have enjoyed more of the animation on the top, but I was too concentrated on the puzzle itself. Maybe making the puzzle a bit smaller so the animation can bring out the entire game at the player's vision.
Besides that, it was addicting and fun. Hope you make a sequel or such =P
