As others gave stated look into fixing the UI scaling, otherwise congrats on finishing the game and submitting it!

The resolution is borked; I was still able to play, but the glacial starting movement speed and low damage made it hard to engage with the power-up system. No audio feedback makes the game not seem as interesting as it could be. I didn't really see a reason to not auto-fire, but this is pretty common in shmups.

Nice shooter!

Nice Game,

You may change the itch.io screen size to match with the one in tyour game (on my try, I got the right part cuted)

On design level, you should maybe give less HP on your enemies at the begining, if possible (or on some of them), It's kind of hard if you miss the first kills or get no bonus from them.

Anyway, its a cool shooter ! congrats
