This prototype is the very close to the final version, which
isn't surprising given it's dated only 9 days earlier. The
only difference appears to be a small block of memory which is all
zeros in this prototype (and in the earlier 1-20 prototype) but
has code in it in the final version. It is unknown what this
extra code does as it does not appear to be called during the
course of normal gameplay. This might have been the start of
an easter egg or some sort of last minute bug fix.
Space! Lasers! Excitement?
These guys suck!
