It's cool to see another rhythm game out. You need to include a bit more feedback on button presses/timing for the player to understand what they're doing (sfx, visual cues, etc). I fought the first enemy 4 times before I figured out how to dodge. Art is a bit all over the place: Cartoonish items, rust/gore walls and enemies - except when you reveal the sterile ship under it, and all of this is a metaphor for a dying relationship. Maybe embrace the mixed media approach and do something like https://store.steampowered.com/app/2134320/ENA_Dream_BBQ/. I didn't hear any music - just the heartbeat. I recommend using some industrial noise at least, something like Akira Yamaoka. UI is minimal - I recommend using a font other than Godot's default.
