Ahhh, yeah, this also reminds me of making a "platformer" on my TI-83 calculator (during class in school, which my teachers hated, of course). Similar to OP in that my code was a twisted mess of a thousand lines of GOTO statements, and similar issues with draw functions... I remember having to manually use pixel on/off in loops because it rendered a lot faster than using an algorithmic draw. Graph mode for less action-oriented games is probably a smart move.
