This gives me Cursed Travels vibes and I love it. So much to do and explore. Very nice pixel art.
I think I did everything, though I never figured out what the upgraded torch is for. The only hint I really needed was waiting on the unstable floor. I thought I was supposed to make the floor collapse by walking a lot rather than waiting. I think you should switch it from 30 seconds to 15 seconds. Also it was nice to look up some reminders about where the temples are in FCPXAV's review. This game could really use a map, especially one with either automatic or manual markings. I found all the Valac shards without any help so I'm proud of that, and I tried to uncover all optional dialog and Easter eggs like turning the shade to gold.
Also, I accidentally lost progress a few times by ringing the bell to get the Twilight Zone ending. The first time, I didn't have a habit of saving very often so I was really lucky that I saved maybe 10 minutes prior because otherwise I would've lost over an hour of progress. You should really make sure that when an ending is triggered, the autosave is right before that ending.
