A polished game, all the text and story makes it feel like a "finished" game. You're not right into the action, which can be a bit annoying. When the action comes, though, it gets pretty hard. The timing for parrying is really tricky (because the animation is too slow), and I gave up when the boss regenerated all his HP...
Didn't see the other levels, sadly, (but based on the screenshots, I think it's the same monster?).
Congrats for pulling this solo, it really feels complete!
