I highly encourage everyone to try out the free SDLPoP port of this game. It has many optional bug fixes and enhancements while remaining faithful to the original.
I'm surprised (though maybe I shouldn't be) by some of the reviews on this page where people seemingly abandoned the game very quickly without even substantially trying to engage the game on its terms. When I put in some effort to learn it, I came away admiring the design of this thing immensely. There's a precision and an austerity here that really tickles my brain. People seem to be frustrated by some unfair deaths, but I believe the game is designed around that well to force the player the learn the levels thoroughly. The way combat plays out is very satisfying to me. Different enemies require different strategies to defeat. Some I could defeat by being aggressive, while others I had to be very patient or bait into attacking and then countering.
I don't put a ton of stock into awarding old games extra credit for being good relative to when they came out, but I am extremely impressed at how well this game holds up. Special mention should be given to the audio/visual design. The game still looks and sounds nice and has some cool cutscenes.
