Portal references in the Waste of Space DLC (and one Earthworm Jim reference).
To start off you will need to reach $40,000 in CrowdKicker funds to open up the Test Chamber.
From the Crowd Kicker headquarters/start head left as soon as you exit. Under the left side of the spaceship pad is a jump pad. Use that to reach the entrance to the Test Chambers
Just some quick notes as you move through the chambers:
-When you get The Tether Device press
to attach the Companion Cow to the attachment points.
-In test 05 Lazors use the Companion Cow to eliminate some of the 'lazor' beams. When you have to jump to the second red button press
to ragdoll and make the jump. Alternatively you can equip the double jump mutator before starting, but I attempted this first without mutators.
-In the repeating loop room wait until the walls are completely filled with cow pictures, then turn around and go the opposite direction.
