Hi.
At first they will be a chest with a few stuff (Saplings or something) you will be in a tall area, and you will need to try work your self higher up with the stuff you have in the chest (like saplings: use saplings make trees use wood to get up. And the first one to get up the high square wall, wins.
I hope you understand what I mean, and I hope this gets made, maybe for a event or something.
Thanks for reading
