you've made another really fun puzzle game that i can't stop playing!! it took me abt 5 runs before i realized that after a certain point i didn't have to actually solve the sudoku puzzle, lol. thanks for making this!
edit: found a bug - i placed a 6 and the boss counterattacked because i had placed a 6 (the ability), the counterattack killed me but the game did not end.
edit2: another bug - a skeleton labeled only staggers on an attack with an 8 actually staggers on every attack except 8s
