Hey thanks !
I believe pressing E for you didn’t work because you didn’t jumped before.
It is totally on me though because I didn’t really said it when the game « teach you » how to do it.
And I won’t lie, I absolutely didn’t knew how to make a border so I tried to put a really big wall I thought it would have stopped player from trying but thanks for letting me know !
Also, why do you think you were jumping too high? Did it makes you jumping over obstacles to easily ?
But overall thanks, it is really encouraging!
