I like the mechanic of only being able to switch directions as opposed to full control of the player character. I think it has potential as a game mechanic if it were placed in a much more robust game. As is, the game lacks an objective and any measure of player choice. I can tell this is an early attempt at game development. I hope you learned a lot and had a great time. Your game made me smile and I strongly encourage you to keep trying new things and improving.
