I could never quite understand the notch puzzle.
You're not alone on that one, that puzzle is responsible for like, half of the questions I've received on other sites, haha. Hmm... maybe I should add a visual representation of the dials to make that puzzle's description a bit more clear.
...dying to enemies that were doing less damage than I had health...
This one though? I haven't heard about anyone else experiencing that before, but if that’s happening, it needs to be fixed! (In the browser version, you should always have enough health to progress if you buy the armor and drink every potion) Do you remember which enemies or rooms caused this?
Also I'm not sure what sword your talking about in the guide since the shop keep has no sword
Yep, I'll fix that right now. I wrote the guide around the Python version, which had both a sword and armor in the store.
