Professor Max is a sokoban series of puzzles. The first 20 are free.  I solved #s 1 & 20.  I want to like this set of puzzles. You have the option of making it 3D or 2D.  Either way, the movement is too slow and I'm impatient.

Perhaps you're a sokoban fanatic and can't get enough of these.  If so, give this a try and let me know if these are good.
