The walls appear depending on how i made the map so its not consistent through maps. but the rule for the walls to disappear is:
On top of the wall is a past player, to the left of the wall is empty, and you need to step back into the board.
this rule is completely nonsense and is just arbitruary since i didn't feel like thinking of something. Though i might add a tutorial if this idea turns out to be good.
also yeah this game was inspired by chess 5d.
Thank you!
