Create your own levels, and race online with friends.
Race online with people from all around the world. The game has a built in level editor, so you can create your own levels and upload them for all to play. There's an easy way to beat higher level players just by adjusting your stats correctly.
You chat with people, you race your tracks with other ppl, and you can use hats to increase your EXP points, it's AWESOME. When will you make a downloadable version on Jiggmin.com? One more thing: Not to be rude, but can I be a Mod or an Admin? You got to check my levels out!
Cons
The only thing i would like is that you have sloped blocks, to make uphill and downhill.
