This is a really cool game! Congratulation!

The game is simple, and cute. Generally a good physics puzzle game for kids.
I do feel it would be easier on a tablet, but that's understandable.
The combination of star collection and time trials, adds replay value.
I don't like the look of the ink squirting (or whatever it is) as it's pixelated and nasty. Collisions with the boxes are strange too.
This problems aren't game breaking or anything, simply unpleasant when I play the game. Your level design however, is marvellous, and worthy of much praise.

Although the game is looking good, it freezes upon ending the first level. I'm guessing a "success" dialog should appear showing the stars ad giving you options to replay, levels continue, but nothing happens.
Please fix for I would like to check it out.
