Fun game! The upgrading made it a whole lot better. Although I think you could just go on the grass on the side after upgrading the car a few times
Thanks for playing, yes the going on the grass can be abused, had planned to add bonuses for completing the levels faster but didn't quite get around to it, if you had any other ideas for punishments/bonuses would be happy to hear :)
Not really sure, a simple way could just be to let the car take damage if it drives offroad for to long, but I'm pretty sure there are better options
Sounds like a good idea, thanks for the input
