Love the art style and music! I'm a huge fan of this kind of pixel art. The map looks really cool and there's a lot of metroidvania apsects!
I played for a while but I got to say that the shooting mechanic is very frustrating: many ennemies are really small and moving up and down while the player can shoot in only 3 directions. Sometimes, I had to spam small jumps to hit a target that is a bit above me...
This shooting thing makes the game quite difficult but I enjoyed it! Well done !
