The music is an absolute BOP! Like legitimately I would love if you put a download link to just the music on the page.
Love the pastel bubblegum look, unique, vibrant and the gameplay reads well.
I might suggest toning down the difficulty, especially at the start. Maybe enemy ships get less health, or the player hitbox is smaller or something...I did have to replay just the first few enemies to the point of annoyance.
Also, while I'm sure it would be a challenge to have the bullets have sfx that wouldn't get grating seeing as how constant they are, it did seem odd that the bullets were all silent and the explosions made noise.
Lastly, I did run into a bug where the music would just stop looping. It started back up upon death. Not sure what caused it.
