The constantly rotating turret was an interesting mechanic. It worked well for the theme. I like the way you had the opposing sides rotating in opposite directions.
It would be nice if the barriers had a bit more contrast with the background. I got caught on them a few times when I was focused on something else and they blended in a bit too well.
I made it to the laser tank. It was a neat increase in difficulty, but I was not doing great before that, and it felt a bit too fast. I like that you have health appear in the fights. That certainly helped me get further than I would have otherwise.
