Thank you! For food, there's actually a color difference between the front- and backside, but I admit it's too subtle when post-processing is enabled. That's definitely a fix I want to implement after the jam. For the snake body, it's very hard to tell (technically the grid is drawn on top of a snake segment if it's on the backside, but that is really hard to see, especially when the snake is moving). Since the snake is an obstacle on either side of the strip, I'm not sure if I want to do something about that, though.
