Great work, very tightly designed package.
My one critique is that I'd like to see more avenues for player agency. Things like the possibility of mastering the space with shortcuts, the chance to pick which charms are broken (at least some of the time), the ability to accrue other advantages or pick a beneficial battlefield.
Still and all, I found this kind of thing challenging too in the space constraints. I love the mutually-reinforcing procedures. A+
