Update 0.9.4

Nearly didn't get an update out this week, and right now I'm really far from my desk, but still: here it is! So this week I've added two new things: the dynamic background that pulsates with the music, and a new song titled Hotline Space for Co-Op Endless. As you can guess from the title of the song, it's somewhat inspired by Hotline Miami: one of the best game/music combos out there. Many thanks to DivFord for helping me with the background effect, without his help there would probably have been no update this week.
