Great concept and a great visual representation of a mobius strip, the audio fits well and the game plays out pretty smooth. Just a thought I had during the game: Is there a way to know when a point is on the other side of the mobius strip? Since they look the same and you can't know until you pass over them if they're on this side or the other side of the strip, any indicator to tell where we should pick it up. Anyway, great game, and a great introduction to the mobius strip, good job!
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.
