Bullet hell, always fun! If this was your first project within godot, pretty good too.
Regarding the game itself, it had a couple of elements which made it very hard for me to keep playing: The incoming projectiles matched too much with the environment, which made it very hard to follow them. Also, any feedback on you getting hit would have helped. The health bar was on a such a weird place that i only half way found out that it was my healthbar :D
Couple of days in a new engine and this is the result within the time limits: Awesome job!
