I love the restricted colour palette, it looks great together with this really nice pixel art. The game concept is fun and it looks like you chose a really nice scope that allowed you to get super polished with the game. I feel like the UI is generally nice but has a few little quirks: the horizontal buff/item icon list seems to have varying padding in relation to the health bar; the "Combo" text seems a bit asymmetric. I assume you want to highlight the player by having it be bigger but I wonder if you could do it without asymmetric font sizes.
