Forget my previous comment. I finally lucked into the correct starting arrangement for Lvl 14. Not sure if this helps but the first teleport red enters is on the top row, third from the left. it then hops all the way down. The first teleport for green is the top row, forth from the left. it also hops all the way down.
I'm stuck on level 14. I would like to continue with the puzzles, but I'm losing interest in the game. Does anyone have any pointers, or even a screenshot of the correct initial arrangement?
It runs smoothly for me in Win7/Firefox.
EDIT:
I added an option to turn off the lighting effects (open the menu with ESC or X and select Options). With the effects off, some puzzles are gone and atmosphere suffers, but it should solve the problem for those that have the lag.
I meant to disable dropping in the shrine. I'll get right on it.
