The first or second door?
Hint you can change the code of everything that has color. If you're stuck try to find colorful things, that you didn't try to change yet.
Let me know if you want further hints. :)
the first door, actually. i tried setting the initial variable to != false, and tried increasing my own speed to hopefully clip through. i even tried getting the enemy to push me through the rightward wall, but i cant get through anything :<
or, the probable answer: im just dumb and cant figure out what to edit in the door :/
