The animation of the walls appearing is really cool! I'm gonna have to figure out how to do that myself 🙂 I wish there were some way of knowing how far I'm moving when I take a step. Since the camera follows the player, I can't tell if I'm only moving one step, like a chess board, or if I'm moving all the way to the next wall, like in 2048. Zooming the camera out so we can see the whole playing field would help a lot. Excellent concept!
