hm...
I just died the second time and the game stopped running or it did as otherwize the iPhone should have stopped it but it was like an endless loop or something.
Isn´t 40mb too much for that game?
and I especially liked the contrast between the black and white and the red roses in the Gamestudio version of that game. Now it actually is kinda hard to see the roses. You should may make the red more red and/or make their upper part a bit bigger.
The game is pretty hard btw and the loading times too long for my taste.
The always exactly the same looking traces of the sparks are a bit disturbing, at least they were the first round I played the game, one gets used to that...

To me it seems as if Unity doesn´t really fit for such a 2D game...
It is a nice game nevertheless, but there are just still possibilities to improve it.
