Very cool game. I'd highly recommend screenshots and some cover art. I feel a lot of people will dismiss trying the game without them.
The spinning was maybe a bit too fast; I felt a tad nervous doing it. That being said, after a bit of trial and error it felt very cool to dodge rockets left and right. My initial experience was me stepping in a direction at the start and rapidly spinning before accidentally shooting what I later realized was the start target.
The visuals are top-notch for this PS1 style and the SFX were nicely done; 'cept for the revolver which sounded a bit weird. Speaking of the revolver. I don't know why I'd ever switch to it. It seemed inferior to the rifle.
Cool game. I originally downloaded it as a bit of a meme assuming the lack of screenshots and cover art meant it wasn't going to be very good. I was very wrong.
