I just hit the release button on the Turbo Hatchback Time Attack Demo! Go download it and you can play on the first two courses in the game:
⛩️ Sakura Park ⛩️ 
🌲 Redwood Valley 🌲
Super pleased to be able to share some of the game, see if you can beat me (grumpy_pizza) on the leaderboards 👀
Cheers,
Ewan
