Looked very nice, but still needs some more work
Graphics: These were pretty good. The drawings were very nice. The colors were bright which looked good, although maybe they were a bit too bright. The textstyle and color were also excellent. Can´t complain much when it comes to graphics.
Sounds/Music: The music was nice, suited the movie well, but it´s good that you added a "music off" button. I got a bit annoyed by the song after a while. It´s too bad that you didn´t add any sounds in this. I think it would´ve been better if it had some sounds.
Interactivity: Well it had a pretty good looking menuscreen and the turn the music off button was a good idea like I said above. About the games, they were fun to play for a short while, but I got a bit bored soon. I mean, the "build a snowman" game takes too long. The % competed went up too slow. You should speed it up a little. You could also make us use more buttons then just the spacebar. The memory game was easy in the beginning, but suddenly became very hard after level 5. I still managed to get through a few levels, but I think it would be better if in the first two or three levels you just have to remember two snowman. Then from the next couple of levels three snowman. Then four, then five etc. That would make it easier and more fun to play I think.
Overall 7 out of 10, 3 out of 5. Still gave it quite a decent score cause of the excellent lay-out and a few other things. The idea of adding simple games was also good, but they need a bit more work. Also, you could add some more minigames to this. I´m sure you can think of a few more to expand it. Games where you have to collect/catch stuff for example. Anyway, keep it up.
