The bugs aren't fatal you resume your position if you reload the game and you can change the language to skip them.
It's just that after a while it seems kind of pointless, once you figure out how to play en do the Enkou and buy all the skills there's no real goal or challenge and nothing to spend the money on (sure you can get a few consumable but they become redundant by that point), sometimes you get super unlucky on the first turn and lose...but that's it. No real challenge or progression.
