v0.5.5 - Visual overhaul, new characters, physics determinism, and more

We’re sorry to have kept you waiting, but we promise, we’ve got something good for you to chew on today! We bring you the ultimate gift in competitive, animal in ball style racing! DETERMINISTIC PHYSICS! We’ve overhauled our entire physics engine which takes a long time to ensure that when Multiplayer hits you all get the best experience possible. We’ve also overhauled a significant amount of the world backgrounds, polished up some stage visuals, and we’ve got a couple new friends for you to play as well! It’s time to roll up your sleeves and Roll Out!
