A fun little experience, albeit a bit too easy for my tastes. I saved my stamina until that big purple monkey face saved me and it never had the chance to catch me. The path between the Keeper (was that its name?) and the soul spire was too short for a good chase sequence, and the spookster tend to be always in the opposite direction with its back facing me.
As constructive criticism I'd recommend making the spooky thing harder to see before it has seen you (no glowing lights until it's go time) and then just make it faster. Almost the same speed as a running player would make it very intense.
All in all, I got a good chuckle from it and hope to see your work in the next Jam.
(And only now I realize that it has a difficulty setting. Maybe put it in the startup menu next time?)
