The game is actually really easy once you get the drift down good.
But, probably my favorite feature of the game is how that how good the player does not matter. You get SEGA Miles no matter what you do. So achievements aside, anyone can eventually unlock everything in the game. It is just such a brilliant way to keep players coming back for more, but not needlessly frustrating them.
My favorite thing about the weapons is that when you have a weapon, not only can you throw some backwards, but you can also hold the A button to drop all of your weapons at the same time if you have multiple ones, and they go in different directions. It is really such a great idea. But at the end of the day with the final release, I am happiest you can keep the weapons off if you want to.
Also, I think the PlayStation 3 demo will have Big the Cat playable. In this demo if you look on the title screen Big drives up, but you never actually race against him in the demo.
