Have been trying to solve this for a very long time. Also, am missing achievement "Magic x Trick" Any help would be appreciated.

Is there an undo?

I haven't played enough to write a review yet, but I have to say I am enjoying this game. I almost didn't buy it because I have grown bored of block pushing games, but this one has some pretty creative dynamics and a good level of challenge. The graphics are fun as well, looks like South Park or very old games from the dawn of the PC gaming era....
