Really fun gameplay.
My only complaints would be that boosting with right click locks the cursors which could be a bit annoying and caused one or two deaths, and that you could fly off screen but then you couldn't shoot.
Also there's no end screen, the game just instantly restarts. So showing something there, and maybe your current and best score would have been nice.
The shooting sound was satisfying, but the tinny hit sfx was a bit annoying, and I wasn't a fan of the music.
