Too Long; Didn't Read
Brazilian Evelyn Stender built a skateboard game on Christmas Hackathon. The game is a work in progress and he's aware that he could've done it in different (and better) ways. Every 10ms it is checking if the skater is hitting (overlapping) the rock or the scooter or the rock. If so, the game updates the highest score if needed, and add a "try" button. I pause every 10ms to learn about how to make the game more complex.
