I have probably just move backward a bit and fall imediately. I have well find the objective but as we doesn't see anything and moving or shooting balls doesn't change lighting condition it's barely just a matter of luck there is no clue at all. That deserve your game as we are just lost.
By the way if you got a bit of time i would apreciate to get your feedback on my proposal. : https://itch.io/jam/kindred-community-jam-6/rate/989211
