Thanks for review!
And can you tell, what's off with the sound?
My bad, should have specified.
The main thing is that the enemy explosion sound is quite quiet compared to the music. Playing other shmups, I'm used to it being more punchy. And then the siren for the boss arrival was a little too loud I think. I was also under the impression that the gun fire sound was super low, but seeing other reviews I guess it isn't in yet. That should be all.
