Glad you liked our game! Sorry about the browser version, since Unity (our game engine) can't run video files locally in browser, it streams them from a server and that seems to result in it being a black screen 25% of the time. The backgrounds are fixed on the downloadable version since the video files are stored on the machine for that version. Happy to hear that this didn't make your experience with the game worse and that you even enjoyed it even more :). Thanks for all the kind words!
