Truly amazing game. I've been using stereoscopic imagery on my phone for some time and I tried to developed a game using stereoscopic vision, but using the textured background for making the elements pop is ingenious. I can imagine when I play the game I look like I'm staring at two colorful animated boxes haha.
The only thing I recommend is increasing the level of separation for contrast, adding more varied coloration within the frame to help distinguish the boundaries of the player and obstacles, and to decrease the texture scale.
