Thank you! Yeah I should have made the goal a bit clearer at the beginning. I tried to drop some hints in the ghosts' dialog if you kept talking to them.
I found the ghost moving sound to be annoying too, but couldn't figure out a replacement I didn't also dislike. I ended up adding the music and a volume slider specifically to turn down that ghost sound in case it was too annoying. 😅
The ghost movement was tricky. In my testing the only time I saw the enemy ghost get stuck was on the player, but it usually fixed itself. So I was surprised to hear that you could get really stuck. I think I should have made the kill collision box bigger.
