Unlike most of my assembly programs, I made this one on a mobile phone.
Overall the development went fairly smoothly. The techinque I used was the same as in the E1 sheets: page 3 for testing and all the subroutines starting from page 4. I committed to the layout of page 0 at the beginning. I used the Notes application of my phone to keep track of the layout of the program. You can see my notes below.
I wrote clearscreen (4:0), tested it, wrote print (4:11), tested it, etc… until I reached the end. When I reached askguess (4:146), I started morphing the test code on page 3 into the proper main code.
It is hard to say how long it took me. It was several short (5-20 mins) sessions over a few days; I guess overall it was about 2-3 hours. I would not be surprised if it would take 10-20 hours for a beginner to write a similar program.
Here is a very simple mini game for MicroIO:
