Thank you for the detailed feedback!
Don't worry about the wisps! They are already dead, you're just helping them pass on. XD
They were added to the game as an element to throw the player off and as an unpredictable obstacle. I had to add some chaos in there because the game felt slow and boring without them.
Of course, having a large number of play testers would've helped figure out ways to tune the game so that it hits the right spot.
Oh and about the death cry... the original plan was to add a silly Mint spooky voice going like "wooo~" to make it sound funny and playful but I didn't have time to go hunt for it so I ended up using the next best I could find during the limited time of the jam.
I'm glad you managed to see the ending scene! I put it together almost in the last day of the jam. I would've loved to have someone voice act Doki's lines but unfortunately there wasn't enough time to do it.
Once again, thank you for playing! :)
