Big thanks for playing and analyzing my game so deep, I'll notice most of advices and improve the game later, especially the difficulty and level design to make it easier to go through them, but I'm not sure I'll change the movement controls, because the idea was to make player fell like something wrong is with his body, and so he'll need to study and start feel his mass correctly and control it well, just like a parasites, but thanks for such a clear comments about the camera, other controls and etc!
