Never would i have thought of how to implement "chicken" in a game, but you did it. Incredibly creative mechanic deserving of 5*. I had a lot of fun with this. At first thinking that I just needed to start moving after the CPU did, but you've got that base covered and this strategy doesn't always work (nice work).
The concept itself is novel and entertaining enough that I can see this as a cool multiplayer game for mobile, to be played at parties! Well done!
