Thanks, I'm glad you had fun! There's a known bug where the game does not handle winning correctly that I had fixed in a version but I just, didn't upload it correctly. (Honestly, I'm impressed you got to 1d2, there's another bug with the fights where if it goes to multiple rounds it freezes. That's the big one that had a fix that I just, forgot to upload the update.) Also, for a peek behind the scenes, the way the battle works right now is you have to roll below the value of whichever die attacks, so if a d20 attacks you have to roll below a 20, so yeah a lower die will always beat it.

That's a fair point with the d100 and d40s. I'm not sure I've ever actually seen a d40, I just picked it because it was a nice intermediate between d100 and d20. I wanted to do one of those big ball dice for the d100, but it would be hard to make the numbers readable and the way it actually draws them behind the scenes is isometrically projecting a list of the sides from 3d, so I'd need the vertex coordinates of whichever shape I use. (I did it that way so that hopefully in the future I can make them actually visibly roll.)

Thanks for your feedback!
