Finished the game without taking the health or shot cooldown powers. A few small glitchy things with the music and I think the way shot patterns interacted with Turret changing directions in phase 1 (it would fire three bullets in 1 direction in a diagonal pattern rather than the 4 way horizontal and vertical cross when Turret reached the side of the screen to turn around).
I think my main criticism is that, given the game jam's theme was countdown, I never really felt the presence of the timer. Maybe this is because I naturally play SHMUPs rather aggressively, but I never hit that 30 second wall, and by the time I had the speed and shot distance upgrades, I was basically at teh mercy of my own understanding of the bullet patterns rather than the timer. That doesn't detract from the actual game quality though.
Neat artstyle I felt the personality of the antagonist really well.
