Metal Head prototypes

There are currently ten prototypes available for this game. In addition to the ones below, there are also prototypes for the 13th, 14th and 20th of December that need further looking into. Actually all of these prototypes need more looking into, as I imagine some of the levels are different (and the earlier prototypes might even have more levels, as their sound tests list music for a seventh and eighth stage -the final only has six stages) but I really don't care for this game.
