Wow :D Thank you for playing my game. This was my first submission for a game jam and i would never expected to get this much feedback :)
For the movement: When you turn the game all snakes change their direction, such that the blue snake (you) will always move down and the red snakes (enemies) will move horizontal in opposite directions.
Btw, i really love your channel trailer on youtube. It’s so entertaining and joyful :D
