I FOUND GLITCHES
EvilObjective is good at making it, I'm good at breaking it.
+If any of these are intentional, then reply. =)
Stand On Moving Platforms without Moving Glitch
On any floor with moving platforms, start on a moving platform. Make sure your spawn is close to the platform, or it won't work. Immediately die and go onto the platform. Ta-da! You're on a moving-static platform now!
Go in Portals, No Effect Glitch
Start on the second floor (or any floor with portals), and get in a portal. Then go the opposite way of the portal. There, you're not teleporting in the portal.
Comment if you found any more!
