Thanks for playing and for the feedback! I love the idea of the red blocks have more of a penalty, or maybe having different types of penalty blocks that could appear. Regarding the sound, it should play a nice little beep each time the snake moves. I was worried about it being too loud and annoying, so I dropped the base volume down pretty low on the sound effect. I wonder if I put it too low and it won't be audible unless a system's audio is up high? I wanted to include a settings menu with a volume control, but I didn't have time.
