The music is super fun!
The visuals feel a bit mismatch overall but it doesn't interfere too much with the mechanics.
On the gameplay side, I found it too hard to keep track of everything going on in the screen with all the spread out formation and I just set it to clump together in front of the cow and call it a day lol. Probably not the best strategy but it's too overwhelming for me otherwise. Also I found some formations are less useful than others like the circle, because the enemies are coming at you from the right side so why would I want so send ships to the left side behind me. Or at least that was my thought when playing the game.
