Thanks for playing! This is a lot of great feedback, thank you!
I threw together a lot of content for a December game jam and tried to finalize a whole lot of loose ends for FFS, and you've found some more loose ends which is appreciated. I was inspired by the King's Quest V game, not realizing the level of effort required at first. There's no way this would have even be possible if I didn't make use of a tool that converts photographs into pixel art (phixelgator).
The idea with the 2 air balloons is that the *unmasked* elf has an alibi as it is in a separate air balloon than the ghostface. The ghostface-masked elf has stolen the Christmas presents. There will be 1 elf though that is not accompanied by a 2nd air balloon, this is the only 1 of the 24 elves that doesn't have an alibi, so it is the culprit and you must return to find him again once you have a mask scary enough to make him drop the gifts. The air balloon thing is a bit cheesy, but I was trying to cut corners and air balloons can move as they please in front of any photograph without looking mispositioned over the image. While I've tried to hint at this in different ways, it might need to be explained specifically at the start of the game.
Great feedback on the red dots looking like you don't go there when toggling the help screen, but really those are the exit points that you need to go to.
I tried a few different approaches/algorithms to the edge detection, I'd be curious to learn how KQV did it.
Visiting the vampire (for the coin) first before the hunter (for the werewolf mask) was an oversight. I think my narrative text assumed you'd go to the hunter, then the vampire, and then back but that isn't explained well when vampire is visited first. Great feedback I can improve on for that.
Glad to hear that the music integrated well with the gameplay :-)
