Really solid job! Pretty tight vibes, and the combined health/ammo creates a really engaging dynamic. I really enjoyed the sorta risk/reward play you get when you need to keep your shots to a minimum to reduce how much each fight "costs" you - with every miss and every hit you take increasing that cost. The parry mechanic being a way to further increase the risk/reward factor along those lines was a really smart move, I think.
If I had to nitpick, it'd be issues with the map being a little unclear at times - and with the art direction of the game some of the areas felt a liiiiiil same-y, which made the map's accuracy that much more important. Also the parry-check guard felt a lil unintuitive, but conceptually I like how it functions as an implicit tutorial that the parry works for melee & ranged attacks both.
Overall, great job!! Big fan of this one.
