Playing through it right now, and man it's so good. I love all of the little touches you put in, like how (possible spoilers)
Edit: I do have to report a glitch, though. When I try to enter the Macro Zone, the game reboots to the title screen, except everything is horribly bugged. Pressing start does load the file menu normally, but I can't ever enter the Macro Zone (and complete the game).
