Hay DEVs! I pulled one out of my arse and actually did something constructive!
I made an parkour video for you guys so you maybe can fix it a bit easier! hope it helps!
It includes parkour, pixel walks, hide hide spot to some of them that should be fixed, i think.
Some of the spot you can probably pixel jump on a bit more on to get a bit further on, i did this kinda sloppy jus to get it done
Hope it helps!
