How to bypass creative device limits!

bump the barrier limit up, it’s too small for a single ULTRAKILL level (and no, that is not hinting to anything, I cannot code that.)

Also, for barriers, there are certain Unicode characters like ▐ and ▀ that you can use text for , and you can use geometrically simple props like ad bases and metal briefcases, tint them black, and then set their transparency to the minimum.
