Ask HN: 2D Game Programming

How do I get good at 2D game programming quick? I'm currently super deep into web and haven't touched anything else in a decade. Years ago I wrote some game cheats in ways of simple aimbots and whatnot for Doom and Quake but I can't remember anything related to games at all.

What are some starting points? Websites/Communities/'go-to' texts? I'm not looking for 500 page books but maybe YouTube videos or some quick starts to get my bearings again.
