im stuck at the part with the eyes and the narrow hallway
This is the hardest puzzle by quite a bit--it requires you to use everything you know about the spellcasting system to create a contraption that will help you escape. You won't ever be able to walk down the hallway, so you'll have to find a way to warp yourself past the eyes. The scroll contained in the chest in that room gives you a hint about how that could be possible if you can decipher it. Also be aware that its easy to get softlocked here, so remember that you can press Delete to escape a softlock at any time.
If you want me to give you a less vague hint, let me know.
P.S. If you want to quickly get back to where you left off after exiting the game, you can hold down Shift to walk through walls :)
