I finished the DOS version under DOSBox and it worked great for me, but I’d never played the game before so I couldn’t say.
I didn’t use the F2 save patch, which created an interesting play pattern. Most of the time, the actual shooting mechanics are just a waste of time. The way through an arena is movement-based or sometimes one specific enemy or piece of the scenery to shoot. Everything else you can parachute or turbo past. I really felt that on a second full run of the level.
So as a shooter, I didn’t like it much. The chain gun was slow to kill enemies, and the sniper rifle seemed too slow to use most of the time. Too many arenas would just infinitely spawn enemies until you leave. As a sort-of puzzle platformer with mild humor it was pretty smooth and enjoyable.
