Had a lot of problems playing the game on my browser (Firefox) thanks to a couple of issues. First of all, after the second cut scene, my mouse cursor is no longer locked to my game window, meaning that I can click out of the screen as well not be able to do complete 360s and look up or down thanks to the mouse getting stuck on the edges of my screen. Might be a good idea to test your game in browser as well next time.
Unfortunately I wasn't really able to play the game thanks to it being broken.
