WOW!
As someone who played the original as a kid on my C64, this is so, so, so good. In fact, I have reviewed over 50 games in this jam, and played about 70 in total. This one is surely the best. I doubt very much that I will play another game to match it.
Your game is so faithful that I even tried the cheat code that i STILL remember from the original - type YGRO (ORGY backwards) on the title screen.
Amazing game indeed, and for me, the winner.
