My friend made a die roller in Scratch for his D&D campaign. I don't like his so I made my own that supports natural number die sizes and natural number die counts. 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.
I would like to thank my friend, Mr. S, for making a terrible dice roller, inspiring me to make this! If someone can find a universally accepted notation for advantage, disadvantage, modifiers, &c. I'll add those. I'm too lazy to even find if they exist.
