This game is beautiful. I loved the sprite work and animation. The music track and overall sound design is fantastic, and the boss had some interesting and varied attacks. I even like the time you took to set the scene with the opening.
I really struggled with the controls though? Can you attack after jumping? I found myself just playing evasion the entire time because I wanted to see more of what the game had to offer, but the combat itself didn't touch the polish of the rest of the game.
Really solid entry for a solo dev. Great work.
