Gameplay: I noticed the enemies react nicely when they take damage
Story: Since this looks like it's made for mobile, players there usually want fast, quick gameplay. It might be worth cutting back on the story and focusing more on the gameplay itself
Visuals: The mix of pixel art and AI-generated art felt like the weakest part to me. The two styles don't really match, and it breaks the overall look of the game. I'd suggest sticking fully with pixel art
