Can vector graphics be used?

i believe so. as long as it has the 2-color pallete

Vector graphics is a cool idea :)

I assume anything is allowed as long as only 2 colors are used

Thank you for answering me, I can now think of what I can do.

If you do, be mindful of anti-aliasing, as that can introduce more colors than just white and black. I'm not sure how much of a problem it is here, but I'd recommend turning it off if you can.

Edit: Nevermind, apparently anti-aliasing is allowed in this jam!
