This is such a unique concept and perspective for a metroidvania game. The 2.5D perspective and flat character art style reminds me of the Paper Mario games. The old west is a really creative choice of setting and you added so many little details that reinforce this atmosphere and aesthetic, like the revolver ammo counter and the hawk double jump. As others have pointed out, though, it was really tough to control. Shooting is difficult to lineup correctly, movement and jumping is a little awkward, and ledge detection is very inconsistent. The camera's slight perspective shift when moving left or right can also be really disorienting when you are strafing a lot. But if you work on polishing up these bugs and game feel issues, I think you will have an incredibly unique and inventive game on your hands!
