As enjoyable as it was...
I'm still giving it a 0. What's the point in having a brilliant concept to a game and putting so much effort into it when most people will play it once, die and then never play it again. You need to be able to save your game, if you can't then you just wasted your time and mine. Why would you possibly put so much work into something just to have it wasted because it can't be saved.
It gets a 0 from me overall, sorry. Brilliant idea bad execution.
