I remember playing an earlier build of this game during the RETURNERS jam last year! It's cool to see it return again for this jam.
The amount of detail and effort you put into this project is very impressive, FeverDev. I love all the custom graphics that you made, and it's satisfying to explore when you know there's some kind of secret to be found in each map.
The soundtrack is awesome, too. Did you compose it yourself? Edit: After downloading the soundtrack, I realise now that you did, so a better question would be how did you make the music? I'm curious to know which software you used.
