Awesome to see a whole cutscene! Was not expecting a boss fight game with this theme, so absolutely awesome!
Two things I'd maybe think about if you continue this game, or for a future jam:
- Would be nice to have a volume slider, and for it to save your values in the pause menu when the scene reloads (In Godot you can probably do this using autoloaded scenes, aka Singletons: Singletons (Autoload) — Godot Engine (stable) documentation in English)
- Having some variation in the Player's ability would be awesome! I'll admit I didn't get passed 60% so it could be there, but maybe like powerups you can pick up that give you a short burst of rapid fire bullets would be cool, especially if you have to take a risk to get the powerup
