maybe, but surely if my starting point was bad, I wouldn't be able to progress through one cycle? My start point was the 1st square in the room on the left (after the entrance which is only one square wide)

Haven't finished yet, on level 10 now but this was the first puzzle I needed help on. I had the clue, and tried several different ways of using it. I kept trying to strafe left-right instead of using the left-right sides of the hallway.

This puzzle was the most difficult for me. It took me a couple of days to figure out. I thought I missed something earlier and the area with the ice lizard in between did not help at all.

The funny thing is that I thought the the hint was meant to be used in the checkered room, which also took me quite a long time to figure out....checkered...LOL.

My perseverance paid off in the end and I was so happy when I managed to pass this hellish puzzle ;)

It lets you get about half way before resetting. I think you can just run straight to the half way point even, though I don't have a save handy to verify that. If true, it's probably set that way to prevent you from getting it through trial and error.

Anyway, your first step into the 2 wide part counts as your first left slither. Start counting from the last 1 tile wide space (this caught me for a while, too, couldn't figure out what was wrong).

thanks nesoo, I started the game new snd the second time i went through without a problem
