Thanks for your feedback! I'm very glad that you find these issues. It is intended to leave a black "gap" while eating up the orange, in order to force a player to make some difficult movements (like a sharp turn) to connect the route. The yellow food at the cross issue is known and hopefully a better spawning algorithm can avoid it. Currently you can only follow the pink route without any digging to eat that food, or keep eating fake(orange) food so that more yellow food fill the neighboring areas.
Music & sfx are also what I wanted! Thinking to include some electronic styled pieces.
