Wow great tutorial! It might just be me, but wouldn't it be more intuitive to start with the Diagram of the "game loop", it's seems easier to understand the program that way.

As someone who isn't a game developer but has dabbled, I think introducing the concept of the "game loop" as early as possible would definitely be beneficial.

Ha, nice! Played this to death in my young years :) Also: Shooting Gallery...

I think I actually played Haunted Mansion at a party my dad took me to when I was super little; I rediscovered Dangerous Dave later. Never did get past the "outdoor" level...

First game i ever played, i wouldn't get off the computer till i finished it, good times.

I have actually never heard of the game before, but the name "Dangerous Dave" rang a bell: https://youtu.be/ULdEynOA9Qg?t=197

Not to be confused with Rick Dangerous, which is the inspiration for Spelunky.

Not to be confused with "Super Dave" Osborne, who passed away earlier in 2019. https://en.wikipedia.org/wiki/Super_Dave_Osborne

Not to be confused with Dave Grohl, who broke his leg live on stage, still finished the gig, then had a throne built that he sat on during the following concerts.

No... I had no idea.

and time keeps chipping away at the pillars of my youth...

I was actually thinking this would be about Rick Dangerous renamed for copyright reasons.

I'd love to play slightly modernized Rick Dangerous with some new episodes.

Maybe I'll need to check out the Spelunky thing. :-)

I dunno about new episodes but on the off chance you don't already know about it, XRick (https://www.xrick.net/) has been around for donkeys' years.
