There will be more cars and tracks. I've been adding them as I build out the game.
I'd like to do split screen multiplayer as well, but I want to get the single player completed first.
I am in the process of implementing various skills that give boosts, including the classic nitrous boost.
I don't have plans for any weapons, but I do want to try to cover many different styles of racing, so we'll see what the future holds.
Thanks for checking out the game and providing feedback!
