I loled at 'meme' screenshake strength.
Goddamn, this reminds me of a few years ago when I was outright obsessed with shmups. This game kicks ass, looks and sounds amazing too, honestly would say it's one of the better looking and playing indie shmups I played, and I'm comparing it to stuff like Blue Wish Resurrection and RefleX. The only suggestion I'd have is to have a speed slower than the slowest you have right now, and to have 'speed up' and 'speed down' as two seperate buttons as an option.
