Restrictions:
I'm quite hesitant about you restrictions score... Since, you know, you use way higher graphics. But then again, that Nokia game was perfectly 84x48. (I didn't measure, though.)
Other:
The game had nice visuals outside of the Nokia game, and it was strangely funny how the thumb worked. xD The idea of a game, where you have to move like this, positioning you finger on the buttons, is awesome... Yet again, this adds a lot and is outside of the limitations...
Overall, this is a hilarious game, with nice levels and neat graphics. I really enjoyed playing through it! :)
