Hello. Seems really cool, so far, but I think you should work on the controls as soon as possible!
Since the controls are so unfamiliar, you should probably give the option to keep the moves on the screen.
There should also be better feedback on the input - I never succeeded in the special "snake strike" and I have no idea if my button press is too early, too late, if it is registering at all.
Finally, since the movement is based on "motions", perhaps using the analog stick on the right would be better. Pressing a sequence of buttons on a gamepad is very different in each direction and the analog would maybe help.
These are criticisms quite apart from the game's quality. It's just that there should be a smoother way to get used to the controls!
Good job so far! Cheers. :)
