Good work! I appreciate the old book art, it's very pleasant.
The d6-only approach is great. I was initially wondering about the 13 - two stats approach, but it makes sense: you'll always have at least 1 HP. It's always nice when randomness in character generation has a counterweight.
I'd be excited to see more of what Bascinet has to offer, given there's so many options to go from here. If you ever do a print version, I'll be there!
