I think 1 hand is more fun. Maybe if you could increase the sensitivety or something, or being able to decide your own neutral position beforehand, it might improve things.
Also, the menu system could be the worst evar. There is not much hope for people designing a menu system that sucky.
I think the only thing ridiculous with the control scheme is the angle you have to hold the controller in order to move forward. It makes things more complicated.
Going back to anologue stick control doesnt seem like an option to me. The Wii way is much more funny.
I think you should go with a easier rating system, since one point up or down doesnt matter much in the 0-10 system.
Anyway, I will try rating Sonic.
A classic game, with great controls, and good level design. The sense of speed is brilliant. 4/5
The more simplistic dungeons were the most funniest I think. Too complex level design can hurt the overall enjoyment.
I also like to see a more un-linear progression, as well as the possibility to take several paths when moving to a destination, in the next game.
