It's always the little things... I'm not very good at arcade games even though I really like them. This one is no exception (my max score was 88 millions) and I don't know if you did it intentionally but the sh*t score calculation actually makes the game better imo.
In some runs I was just trying to survive the projectiles which led me to the point where lights were out and enemies were harder to dodge. In other runs I tried chasing the bullets to hit max combo and spin a lot which led me to a really good increase of points before the lights were even out. This game really fits the theme and if there was a jam about "courage" it would fit really well too because here the player is encouraged to brave the bullets to keep the numbers going up.
I also noticed that when you don't spin the music is really simple and while spinning it gets more catchy, and I've downloaded your project only to see that you don't have actual sound files (except for the Juniper serious one) but you're actually mixing the song from code? I don't know much about all this but it's seriously impressive.
To get back at what I've said in the beginning: I think it's a good thing for the score calculation to stay "sh*tty" like that: score increases exponentially when spinning with really good combo count, in a way the player can't really intuit well. That stops them from trying to mathematically beat the high score and encourages them to just stay in the zone. This was exactly what made the charm of old arcade games where you look at the scoreboard and wonder how the best scores were insanely huge.
Anyway, enough of my rambling, all I have to say is that this is a submission you can really be proud of.
