I love the colors! The visuals are really nice, and my only real complaint is that it's hard to tell what's fighting and what's background at night.
I think something's off with the time placement? It's not aligned with volume and bumps really close to the edge.
It also feels like everything's piling up on the top of the screen. The buttons are weirdly uncentered, could center them relative to the friendly health bar but it doesn't seem like it? The health bars look kinda off thanks to the level display.
Combat feels nice, sounds nice. I think the game loop is okay? nothing jumps out at me as being off.
