This was one of the first games I played of the jam submissions. Got the link back in Discord and felt like I had to leave a comment ;) .
Really fun puzzle game with the added stress of the sun being an active timed element. I did get a jump-scare when I first lost a level I did not expect that sound at all xd. Was sadly unable to beat the last level, the timing was just too hard for me. Got very close twice. ( Vampires didn't burn fast enough :P )
All I could suggest is to add more levels and make them skip-able in case you get stuck.
