For a total conversion mario 64 hack this is definitely impressive, but the way I played it I can't really recommend at all. This hack was intended to be played on emulators, but I played a conversion that runs on the original N64. The level designs are neat but there isn't really a proper difficulty curve, some levels are significantly harder than others and the levels demand much more out of the player than regular mario 64 levels. On the actual N64, the framerate is horrendous with some levels reaching an absolute crawl in FPS. The N64 conversion also has a broken game over room, which makes lives absolutely imperative to have enough of. The life thing becomes a huge problem later on in the game as more and more levels favor bottomless pits under everything, making dying extremely common. A lot of my time was spent grinding for lives... One of the stars is also broken in the conversion, making a 100% run impossible. I'm sure with an emulator that has both save states and a stable FPS that this would be a solid little fan game, but on original hardware this is an absolute mess.
