You can't do d[size] or [size], you need to do [count]d[size], so to roll a 6-sided die you need to say 1d6. If you don't, it will break, I could fix it, but it's not my job to make life easy for people who can't read instructions. Don't make the die count astronomical, it even breaks run without screen refresh so I'm just not going to deal with it.
Mr. S told me my project still sucked, so I made it "æsthetic". Personally, I prefer my acetic die roller, but this is definitely something. I spent 25 minutes looking for art of fey I liked that wouldn't get me banned off Scratch and I got too tired so I just made a Will o' the Wisp.
