I found this to be an all-rounder, great entry!
Having different ships with upgrades was pretty cool, and the enemies were very large and yet didn't get godot to lag, which is impressive.
The music was so zen and relaxing wow. I can tell you put a lot of thought into the sound design, though as mentioned earlier sometimes there is too much sound.
The controls, and ship speed are very intuitive and allow the game to play out really well.
Adding some random downgrade on the ships as they continue to fight would've been a great addition to the theme. For example, the laser ship could start out really start, but as its laser overheats, it becomes unstable doing more damage/piercing but firing slowly in a curved path until it gets repaired.
