Hello. Is that happening while you're "attacking downward"? Cause that is probably because of a "button placement mistake" on my part.
When you kill the last enemy in the scene a success screen pops up with 2 buttons that lets' you either restart or quit the game.
Sadly.. if the last enemy is the one that needs a down jump to reach.. one of the buttons results directly in the middle of the screen and it's very easy for it to be clicked unknowingly if you're button mashing.
I found this mistake after the jam submission time was already over so I can't accomadate it right now but I will definitly adjust it after the rating period ends and I (if the game gets a good spot in the jam) start working on expanding it :)
