space-shooter.c VS rogue

You can do something like this, but way less polished and stick to one platform: https://github.com/tsherif/space-shooter.c/tree/master

Otherwise study real, mature, well-written C programs. There's a wealth of techniques and tricks that aren't really documented anywhere, but rather picked up from others. Recommendations off the top of my head: BSD utilities, musl, and SQLite. Or simply study the source for your favorite C software. Also, something good posted here recently: The Architecture of space-shooter.c.

I wrote space-shooter.c as a personal challenge to create a game from start to finish in C without using any 3rd-party libraries and wanted to share the source as a reference for anyone who's also interested in this type of game programming. The source code is heavily-commented, and I'm also writing a (still WIP) architecture guide that goes over the design decisions and details I learned about working with OS APIs in C: https://github.com/tsherif/space-shooter.c/blob/master/ARCHITECTURE.md

The original Rogue was commercial (Epyx sold it- https://en.wikipedia.org/wiki/Rogue_(video_game)) ) and the code has been released (https://github.com/Davidslv/rogue).

Rogue, nethack, and Abuse come to mind, and then pretty much all the old id software stuff, along with the raven engine. These SDL tutorials might be of interest to you too, they are basically in the format of game sources with detailed explanations.

Rogue

Basically the idea is to take this source code: https://github.com/Davidslv/rogue,
