Hard to test but Bug 8: I think using the lighter on the paralysis demon will just crash the game with a fatal error. Of course it is hard to see the paralysis demon in the first place. Though with that said I try such during the well event, I can't tell if the lighter is just generally crash prone in that area or I accidently toss the lighter at the demon one time but my first crash in the area seem to be exclusive due to the lighter and maybe not the paralysis demon guy. It was only the 2nd time when I intentionally try using the lighter on the demon did a crash happen right after but the demon may or may not be related to the crash. Also while not a bug I have no freaking clue what you are meant to do in that area or even if there is anything you can do in it. If it meant to act like the 7 skulls event where it softlock you until you get bored then maybe remove the visible ladder on the 2nd hole. It giving me a sense there is a way to escape but I haven't found the correct solution to it yet. Event aside I feel a crash isn't intended so likely a bug. If the crash is intended then you might need to add a new "error" message for it or even better have it act like Gooseworx's death screen.
Edit: Bug 9: Almost forgot about this one but achievements are a mess for whatever reason. The location based achievements (Hole as an example) only unlock if you haven't save and reload during that run. Oddly enough you can get achievements just by sleeping in your bed. The Hole and White Object achievements were unlocked just by passing the days away in bed. As a dev it would be far easier for you to debug the achievements. If I have the guess the first load of the map and the save/reload version of the map doesn't sync up too well sometimes. Bunker near base where the passcode is 8008 and the eatable drive at the spawn hut doesn't work correctly on the first run of the map but the achievements does. The reload version of the map disable location based achievements and but also cause those two things work correctly. I know it may be a lot of extra worth but for future proofing the game and to make it far easier to test and debug you might want to create a single state of the map even if it just the game automatically loading, saving, reloading on the first load up. It would prevent future oddities. Already seen people getting confused on why 8008 suddenly don't work on the bunker.
