Interesting- you can use this to make 1-way pipes!
Just asking, for gears, what does
do? Or is it just a depricated feature.
Also, 2 bugs that slipped into of your puzzles:
1) on gears-stop.puzzle (stop), you don't really need to stop all of the gold gears- just make sure they are all going counter-clockwise
2) on flywheel, the L-pipe the faces up and to the right spews steam out left and down!
edit: in animation, it seems that POSKEY goes x z y.
Also, in the rotate finish action, shouldn't rot0 and rot1 be more like rotx and roty? just asking...
