Well, the game currently *is* modularized.  In fact, the executable is 
currently split into multiple parts, but, currently, all parts are loaded in at 
once.  The main executable loads first, then two stubs loaded into the first k, 
then some strings and 
misc. data behind the I/O and kernal ROM to be accessed using my cc65 Hidden64 
library.

I used to comment extravagantly but recently stopped.  I don't know why.  :(

Well, I have my own input routine called AltInput for cc65.  It is a front-end 
to my CBMSimpleIO library.  Both are at https://sourceforge.net/projects/cc65extra/files/ui/.
