Great implementation and graphics (my only irk with the gui is that I would have liked to see my games separately and with more info on how much they've earned etc).
The only downside to it overall is that I've played a few games like this before (I can't remember the names now, where you unlock for example the Spocktrum 32k, how to do text based games, xyz coding etc and then combine it all).
I have not yet played all the entries, but this is so far the one that has entertained me the longest.
5/5 GameStars with following the theme!
