The camera movement issue is caused by your CPU being too fast. All the other movement multipliers are multiplied by the frame delta time (so that the movement speed is the same on all CPUs), but I forgot to the same for the vertical camera multipliers, I just uploaded version 0.9.2, which contains a fix. I also noticed you were using v0.9.0 in the video, even though the latest version at the time of recording was v0.9.1.
