I'm currently playing through this, and it's such an awesome remake, probably the best I've ever seen. I never managed to get through the original, after playing the second in the series. It was just too janky and old for me at the time.
These guys have managed to make it highly playable without erasing the spirit of the original game. I love the mixed up high poly low Res textures.
I know this title has had a bit of a messy history with kickstarters and delays, but it really feels like a labour of love, and I can see why they wouldn't want to release it until it was ready.
