When I say, I built my computer, I mean I designed a PCB, laid it out, etched it, assembled it, then needed to build a display board to output to a TV, which was another several months of design, etc. And when I had all that... then I had to start writing some sort of software for it! (EG: I had to write software, build an EPROM programmer (because they were expensive) burn EPROMS ..... all to get to the point where I could start working on making an implementation of BASIC!
So, when people complain that "kids can't hack on iPhones" ... well, I think its silly. You buy a Mac and you get a fantastic IDE and development platform for free, etc.
To the OP: Congrats on making your game! It looks very professional. Keep at it!
