I've played all raulgevoel parts now and wanted to let you know what I think. The graphics and animations are beautiful, though the foreground could have been incorporated into the world a little bit better.
This might be just my browser, but there is a lot of input lag, usually unity webgl runs flawless on my pc so I figured this might have been your code.
Apart from that I really liked them, the camera is satisfying and all the sounds are juicy.
