I have made my own attempt of THE BACKROOMS.It's not perfect, but I hope you enjoy it!! Just Pop in my welcome center and you'll see the sign to grab a Landmark. You can also go to the teleporter in the building to the right.

HINT 1:
When you get to the top of the ladder, click your up arrow press your space bar to jump in.

HINT 2: If you fall in a hole, click the ground..

HINT 3: X marks the spot.

Good luck and Enjoy!
