No. Learning anything is hard. It is important to accept this. There is no special explanation or trick that gives a shortcut to learning.
When people say “learning to code isn’t hard” they are also correct, but they are speaking relatively. Learning to code isn’t hard as learning things go. Compared to playing piano, guitar, doing skateboard tricks, juggling, etc… it’s just practice and focus and reading and watching and practice and time.
“Waterfall process” is a curseword in software development for a reason.
To me it proves the person is thinks that a game can be created without prototyping and iteration. In addition to only doing 10% of the work, they are under the illusion that they have done 80% and completing it is just a rote exercise. They have also overdesigned untested features and mechanics which makes any iteration harder. I’d have to break their thing down and iterate over the parts with them while also explaining this to them.
It’s just double worst.
