It's a sweet rally game! Taking Rally competition seriously, you'll need both a navigator and a driver to compete in this game. If your navigator can't read a map, it's all over, if your driver can't listen to instructions, it's all over, if you can both work well in a team, go for glory and win the trophy!!!
A preliminary water body implementation. While the body looks okay for a prototype, it is far from optimum, especially if you collide with it...
