Great idea, decent execution.
First of all i'd like to say, exelent idea for a game, verry creative.
Though if you scambled this on paper, it sounds better than it does right now.
So i'll go over some mayor flaws, wich make this rather unique idea less than decent.
First off all, one of my mayor complaints is that when you lay down pieces, sometimes it just automaticly switches to the "hand" icon wich makes all my pieces fall while i'm still building my track.
This could be fixed by making the tipping "hand" cursor selectable, and not making the pieces fall while building.
Another complaint was that making round turns was verry hard, this may be less hard when the above problem has been fixed though.
And my last complaint is the music, its gets you in the christmas mood but its too repetetive, you could improve this by allowing us to select from different tracks or allowing us to mute the music.
Graphics - 7
They where nice, but they where not exeptional.
Style - 8
Unique idea, but sadly the game itself is still a little poor. Improvement of the game would allow this to be a great game!
Sound - 6
The sound is rather bland and repitative, adding more tracks and allowing us to mute the music would be great.
Violence - 0
No violence, but thats no problem.
Interactivity - 7
This is a game ofcourse, you must do certain things and there is a challange, and you can also choose from a free build mode.
This could be better if more object where added, like tricks or bigger blocks.
Humor - 0
Didn't notice any humor in this game, but this doesn't matter.
Overall - 7
Great idea, decent game. It coud've been better.
If you improve the above aspects, and add more interactivity, this game easly deserves a 9.
