I'm just going through this right now, and it's pretty amazing. I really like how he develops this prototype,
and just writes the code which actually solves the problem first, then breaks it up to try and reduce repetition only after he sees how it looks uncompressed.
Yep - that was a bit of an eye opener for me. He is a super smart guy but if you saw a snapshot of this game source your first reaction would be to suggest a series of (micro) improvements... He explains this style you mentioned here: https://mollyrocket.com/casey/stream_0019.html
