Thanks for giving the game a play! Glad you enjoyed the driving mechanic, indeed spent a fair bit of time including implementing vehicle physics in 3 different systems to try the different options out (landed with: mostly simple sliding rigid body with some custom side-friction to counter slip, along with some auto-righting and drag forces).
Though I’ve got my own vision of the more polished game and features I didn’t get to, I’m curious to hear what you feel are the missing features that you’d most expect out of a polished title like that.
