* I loooooved the music. The instrumentation obviously was way outside the realm of an NES but the instrumentation with the Flamenco guitar and percussion went hard
* The game appears to be quite bugged. I was in the negatives on HP and then would just immediately die whenever anything hit me. The music also suddenly restarts sometimes, and the collision with stairs is pretty finnicky- often I'd just fall through them
* I think the use of dithering on the background is really interesting, I assume you're using that to show the transition from night to day which is a really neat idea. It's very flickery on LCD but I'm very curious what that would look like on a CRT I think it'd be pretty cool. I think the flickering thing could have been solved by stopping it from scrolling/locking it to the camera.
* The game's combat felt like it was BEGGING for a crouch a la Castlevania or Zelda II. Lots of enemies close to the ground (including the rats it straight up looks like I shouldn't even be able to hit), lots of arrows and rocks ripe to duck under. I think it would have mixed up the combat a good deal since a lot of it is standing and spamming stab over and over
* I find it interesting you went with up to jump and left the B button open by default, given it's pretty uncommon for platformers and especially metroidvanias. But I really appreciate the control remap implementation!
* I liked the character art and animations, especially the purple sickle guy he's my favorite
