This is directly related to my "Katamari 8-bit Love" Topic.

Option 1: Mario-like side scrolling (Like the ending of M&MK)
Option 2: Free camera (You can go all directions)
Option 3: 3-d/2-d race-like (Constantly going forward, you go left and right to get items.)
Option 4: 2-d race-like (Same as 3-d/2-d ecsept easier to make.)
Option 5: Mixed gameplay modes

If you need an example, please tell me.
If you have a preferance, remember to vote!!!!!!

edit: I closed this, not because no one was voting, but because I decided that since it would be easier to do, and I could add more extras, I'm going to make it 2D race-like. sorry for the trouble. :(
