This is such a cool game! Great job on the atmosphere and tension. I'm learning Twine right now and am impressed that something like this is possible. One minor bug is that I think inventory persists through multiple playthroughs.
(spoilers below)
After getting a bad ending and starting from the beginning, I still have the Molotov cocktail and am not required to craft it again. This isn't such a big deal, but a bigger issue is if you break the lock to the trapdoor with your axe, it remains broken in later playthroughs so you can't win the final battle. I can get around this by closing my browser, but I thought you should know. Really enjoyed this overall.
