Thanks for playing! Having the dice rolls tied to a resource is certainly an interesting idea - I think it would mean less spamming through attacks to get new ones and more considerate dice choices, but would also make bad rolls much more punishing... definitely something we'll explore post jam.
Although there were one or two details that were hard to parse with your game, I actually got the gist of the core mechanics right away so I don't think you did too bad at all.
