Hi Merx,

The text at the top tells you in the beginning that pressing Q will move back to the previous entry in the log. If you do so, you see that W does the opposite. From there, you can go a few steps further back and see predefined instructions on what keys do what. Then as you do things, new entries are added telling you the effect of said actions.

I thought this should be sufficient as it's literally the first thing you see on load, but I will lay them out in the description. Briefly though, to have it solve by itself, press R to start recording your moves. If you want to stop recording/start over, press R to stop/R again. Press C to enable continuous execution, then press E. That will start iterating from a solved state and stop if/when solved. If you want it to go faster, see Tweak Performance for how to make it iterate more times per frame.

The main purpose of this program is to show that any pattern will eventually solve itself from a solved state, even if in reality it takes a while.
