Phew, got 126 as a high score!
I'm not the *biggest* fan of some of the cursed chests needing a QR reader handy, but whatever. The English is more than fine, and the puzzles are really fun, although I'm pretty sure Silver doesn't rust, it just tarnishes :P
For anybody that keeps dying to cursed chests:
Sometimes the mad wizard doesn't have an extra hint: nothing's loose, there's no code hint, nothing. In that case, just treat it as a "normal" chest, although the mad wizard makes chests that violate lots of rules, there are still a few specific tells for mimics!
