It's actually really good quality. The kind of quality you don't usually get N900 games.

Only problem is there's no snapping feature. You can rotate any piece in all 360 degrees, which makes it VERY difficult to line pieces up, which makes the game virtually unplayable. I finished the first puzzle in like 20 seconds, but my pieces were off maybe 3 or 5 degrees so I lost. There's also no snap-to-position, meaning you have to align every piece pixel for pixel.

Too hard, in the wrong way.
