I was a little frustrated by the movement at the start, but it started to feel really nice as I kept going and adding more guys to my raft! What helped a lot was using scroll wheel to change the direction of my next shot when I slowed to a halt. Most of the frustration from the beginning came from my spin stopping while my gun was pointed in the wrong direction. Some way to mitigate that situation in the early game could be nice.
But once my raft was full and there were a bunch of enemies on the screen this was a blast! My favorite weapon was the loudspeaker. It had such a satisfying noise as it wiped out the area in front of me.
I think a game like this could benefit from some sort of combo mechanic to incentivize chaining shots together, which would naturally get harder and more rewarding to maintain as you spin faster and faster.
Great game though, I had a lot of fun :)
