It definitely can be done in 30 minutes, but it depends on if you are good at it or not... It gets a bit tough towards the ending. I can't recall how long it takes on normal pace on a first playthrough. It's been sometime since someone shared their gameplay of this game with me.
Hey! Btw, I've actually just changed the camera of the 64 one into a better, more modern camera, and added/changed more things like the music, models, and sections of the level design to make it more friendly/enjoyable too.
