We can abuse edges of doorway to get out of bounds
1. Place one portal at any wall
2. Other on any wall close to ceiling
3. Jump and dash into top frame of the portal
4. And now you teleported out of bounds! View attachment Discord_vGF0UB9bqR.mp4
Steps to recreate:
1. Place your entrance Door anywhere.
2. Place your exit Door somewhere where the top of it touches a ceiling that leads out of bounds, this includes the invisible ceiling of the map.
3. Dash towards the top of your entrance Door, more or less above it.
4. You're out.
Entering the Doorway while above the frame results in you exiting the other Door in the same position, (above it that is,) and due to its placement being flush with the bounds of the map, exiting in this manner results in you being placed outside of the map.
