I though that the game has a good concept, but, a bad demo...
The demo is very short, which, makes hard to get more of the idea of the game. I would recommend to do a larger demo, to like... I don't know, level 10? Or something that Indivi (Another game developer) does: Do two versions of the game, one free and other payed. The both of them are similar, but payed one will get updates first, then the free one gets the same update after sometime. And, you can make the payed one have exclusive wmthings, like... More awards, or, more animations than the free one. But, it's only an opinion. The game it's good though.
