This really is a great game, it's a shame the dos version is so technically flawed, even with the provided patches. My recommendation is to seek out a source-port if you want to play. I used BuildGDX and it worked pretty well. There was a crash at the end of a level that had 2 bosses. I had to kill them and then run for the exit to finish before it could crash, so hopefully BuildGDX has patched that by now. If not I'm sure there's a better source port out there somewhere.

As for the actual game, it's one of my favorite single-player FPS games I've ever played. The combat and level design are very satisfying. It's impossible to talk about this game without mentioning the Saturn/PS1 version which has been remastered for all platforms. This is a very different game from the console version, and I'm glad it is. Not because I don't like that version, but because we essentially got 2 great games out of it. The console version is much more of a metroivania style experience and is great in it's own right. But this version has more satisfying combat and great level design. It's more straightforward to get through and the enjoyment comes from fighting through levels rather than progression through abilities. You also don't unlock the ability to reach new areas like you do in the console version. The levels still have a great sense of exploration though. Secret hunting is rewarding and the level paths intersect with each other in a way that's satisfying. I would have trouble picking a favorite between the versions. The PC version is probably the one I revisit more, but the console version had a great sense of accomplishment upon completion. Individual levels are more fun to fight through in this version, but the console version is more about the sum of its parts. Either way you can't go wrong and I highly recommend both games. Both are easily 8-9 out of 10 experiences.
