Worth playing :)
I enjoyed Santa's Rubix to an extent. It was fun, though I had troubles with the limb drawing part... Was too hard for me.
Anyways, the graphics were nice and music was cool. Only problem was that I couldn't load the highscores. I don't think that was the game's fault, though - Maybe my firewall blocks it from uploading or something.
A few suggestions, if it isn't too late, is that in Practise mode, when you finish a toy, it goes back to the Cube but on the first side. Keeping it on the side where you selected the toy you wanted to buidl would be better (if that made sense. Is very insignifigant, though).
Another thing I noticed was the toy that was a red shape that you got the pink soap-like thing, didn't have much clear instructions. I mean, none of them do... But for that one I took a guess and moved the pink this all over the red shape until something happened. :P
Overall, it wasn't outstanding but it was defiantly good.
