My new intro - please be inspired or even copy some code (with credit). "pen:Fill In" code is from @junebeetle, please credit him if you use that. Music: Stay Inside Me by Ocular Nebula (from Geometry Dash)
Generation supports 64x64 pixel art logos, in a resolution of 256x256. I used piskel to draw mine. Generation gets a code but doesn't use it, you'll need to manually update the "code" variable of the intro sprite. Text can be removed, however you'll need to update the "pen:Logo" and "pen:Logo + Outline (Instant)" repeat loops so that the outer nested repeat loop is 16, not 11.
