First of all, I want to thank icely and Joe for posting their playthrough of this game on YouTube. They are great puzzle game players, and if you haven't, you should check out their videos.

So, I was watching their videos, and noticed they found unintended solutions to some puzzles, or struggled in places they are not meant to. In this update, I decheesed the levels with unintended solutions and added guides to some of the hard levels. The tweaked levels are 15, 18, 19, 20, 22, 23 and 24. Also the new level 15 was relocated from level 20.
