I'm sorry it took me so long to respond but I really am thankful that you've written such a detailed reply!! It's interesting to see how youve approached it
Hey, I'm curious about how you handle collisions in your engine. If there's a devlog you've written on it I might have missed it? Are characters AABBs? I don't know if this is 100% accurate but I'd heard that Quake used (discrete?) ray intersection tests against Minkowski summed geometry. Is this the same as what you're doing?
It shouldn't be too difficult to port your input and windowing code to use SDL2. It's just a platform translation wrapper, so you can keep the same codebase and you should be able to compile to Windows, Mac and Linux without really changing much in your build system.
