The core idea is nice indeed, I played it for ~10 mins and for some reason I couldn't find out how to shoot, not sure if it's to be unblocked during the game, my maximum score was 218 and it was hard to dodge with no ability to shoot, I clicked everywhere on the screen including the white button in the middle in the bottom (which I didn't really understand what it does) and still the ship wouldn't shoot, not sure if it's intended by the game.
Also additional thoughts on the UI:
The logo doesn't really fit on my device's screen

And I think here it would better to put the "Play Again" button above and make it bigger because users will want intuitively to press the first button they see after the death with the idea to start over and currently such a button is the "menu" and I was getting back to menu even though I wanted to just start over :)

Wishing you success with the further game development! Hope the feedback was useful 👍
