Very awesome project, especially for a one person game in the given timeline! The visuals fit together nicely and I really like the subtle touches you added to show the beat timing with the edge of the screen. I didn't notice it at first (which is a good thing, as it was non-invasive) but it was helping me time things even when I wasn't paying specific attention to it. As others have pointed out, it falls a bit flat on the theme, but at the end of the day committing to a project and seeing it to the end is more valuable than making sure it fits 100% with a given theme. Other folks have commented that you can just stand up next to the enemy and never have to doge (which you can, and I did), but with the limited time to work on it some things end up taking a back seat like finer balance tweaks, and it's all easily fixable later if you wanted to.
The graphics were lovely and consistent with itself and the tech was impressive! Rhythm games are notoriously hard to get right, especially when you're trying to get them to play nice in a web browser, so hats off to you. There's a chance it was just easy to do with Godot (It's just the absolute worst in Unity for WebGL), but as far as I know, you're a wizard.
