At some point after red sky I probably ran out of fire, since I got camera on campfire and then just found myself in a menu. Maybe I skipped it by pressing something, not sure...
Ladder in the sky was legit spooky, I think i did not find too many things though. Overall game is a bit jankier than it could've been, but my main issue is that traversal "game loop" is rather dull. I mean, there's not much to do or think about, I just check the map, run into the darkness, check the map again, adjust. The terrain is rather plain and unmemorable, so there isn't really any "decision making" to do during traversal.
Also the whole fire dying = game over doesn't really made much sense for me since it is seemingly safe to travel in the darkness (not counting flying bricks, although one stomped me almost near campfire).
I played all of your games and METANOIA remains best so far, although I wasn't able to get past mimics stage lol. So, idk, did I miss something huge about this one? The vibes are there though.
