I think we didn't even have plans for a score, we just had too many other priorities to worry about that :P
We did have a restart button... I have a theory about where it went but, well, it's gone.
But yea, no chance we could've found the time to put another interface element containing a full tutorial in, this was already a pretty brutal crunch from start to finish. There were a lot of more important, and much simpler, things and even those had to be cut in the end. Is what it is, 48 hours is just brutal!
