I have yet to try it. But looks promising for many things, even outside of gaming.
Hell, I have still used Q Basick to make a simple batch, file renaming program, for it was the most simple thing I could think of to use to make a program to do such a simple task with.
raylib actually reminds me of back when I used what was called of as Dark Basic Pro, and the C++ variant, Dark GDK. Both Dark Basic and Dark Basic Pro was cool to learn from. And worked OK. But remaking the same programs to run in C++ with the Dark GDK library, was a game changer, for speed. And when making games, runtime speed, is very important. I think one can still get it and try it for free now. But with raylib being around, I see little point in going back to it, for anyone.
I have a feeling that raylib, could be a much better version of what Dark GDK is. Just raw dog your game via code alone. Make one think in code much more than using a game engine like Unity or Unreal. In a way, the way both are setup, can be a bit distracting with the complex UI and hidden options in menu's that can be hard to know is even available.
But raylib, makes one think of every aspect of the code that makes up all of what makes the game work. And you don't have to worry as much, as with using Unity or Unreal, that an update to either, means part or much of your code is junk after, as what you written is considered unusable in the new update.
Next to noting is more frustrating than spending weeks or months learn how to setup and use a 2D UI in a 3D space using their function call libraries, only for it not to work anymore in a new update. And one must now spend time trying to re-work ones code, to mach the new way of writing a 2D UI in a 3D space again with their new function calls they make you use after the update. Yeah, frustrating, is a gross understatement.
raylib should be far less retraining once one learns how to use it. I just wished I had all the free time I did have to learn it today, as I had back when I didn't have my currant day job, and time consuming responsibility, that comes with living in today's world as an adult.
But if one has the time for it, to make the most of learning it, I do recommend one start off with something like this, than to go to Unity or Unreal. The pay off from one's time to learn it, may not get burned away with what may be added to it, rather then changed as with Unity or Unreal's case.
