You made the mistake of thinking that anyone would care how many hours you spent optimizing some C++ function that does something already solved a hundred times in a hundred different game engines. It's a natural tendency for all programmers. But making a game in 2018 is far more of a creative endeavor than anything to do with programming really. You need a massive amount of top notch artwork, music, 3D modelling, shader effects, SFX, etc. to have a polished nice looking game. That takes either superhuman talent or a large team of specialized people beyond yourself.
