In this 4D racing game, players have full control over time and space. When a player makes an error, rather than having to wait for a "reset" to get back on the track, they can immediately reverse time until they are satisfied with their state. Players can also speed up or slow down time to quickly navigate open sections of the track and carefully manoeuvrer around corners. Most of it was built during the first semester of the Projects in Computer Science post-AP capstone course at Garfield High School as a team of four people. It draws inspiration from the legendary Mario Kart series as well as Jonathan Blow's Braid game.
