G'day Rat Racers,

With this update, I have introduced the Hats system to the game! As a celebratory Christmas gift, every player that opens the game from the 25th of December until the 6th of January will receive a tiny little Santa Hat to put on their Rat Racer. Currently only player 1 will be able to use Hats; a future update may address this limitation. Please note that the System Clock must be set correctly for this unlock to function correctly.

In addition, the following changes have been included:

  • Item balance has been adjusted. The ??? item was appearing a bit too frequently while Portable Dash Rings weren't as frequent as they should be.

    • Portable Dash Ring drop chance: 21% -> 22% (buff)

    • ??? item drop chance: 2% -> 1% (nerf)

  • Significantly improved CPU players' ability to follow racing lines rather than the road directly.

  • Optimised the performance of the Item System; now slight stutters caused by garbage collection should happen less often.

  • Changed the deploy animation for Shields

  • Added back a quirk from an early version of the Cheese item where the player's Rat appears to throw away the remains.

This will be the last update released this year.
