Interesting choice with SFML. Always curious to see what people choose for graphics when it comes to C++. I tried a simple game with that which worked alright, but then I wanted to port to Android and things didn't go very well. I switch to SDL2, where there's more official support for Android, but it's still not ... let's say ... enjoyable. Probably because I'm going against the Android grain in trying to avoid android-studio and gradle. I didn't need those for Windows64, Linux64, ARM, and I'd rather keep the same CMAKE, gui-free dev env for Android as well.
