This is weirdly my favourite thing on the playdate so far. I like to run up to people and shout at them to pick a number between 1-7, and then commentate their folly :}
Thats said! It could be improved if the race track scrolled so it went on a little longer (or maybe you could pick the overall speed so its slower); Id also make the first press of A reset the race, and then a second press actually start the race; sound effects would be cool too!
