First off, this game looks amazing! Great job on the presentation and level design.
There is a reason that games rarely innovate on controls. Trying to reinvent what a lot of pro developers have refined over decades of games is only going to limit your audience. The players who want to pay for this are the same players who like other skating games. Player expectation is very important if you want to be succesful. If a lot of players are immediately turned off by your controlls, you are doing something wrong. Players are not going to say: "Wow, this game controlls really weird. Let me go find a video where the developer explains his philosophy about these controls... Now that I understand his vision, its all good." The more likely outcome is players will think it feels bad, play for a few min, then leave a negative review.
This is the same for any genre. The reason that 99% of every racing game, every FPS, every MMO, every fighting game, every 3D platformer all controls the same is based on player comfort and expectation. It is impossible for players to be immersed in a world where they are not comfortable with basic movement.
I think you have a lot of great ideas here and a potential hit on your hands. I hope it doesnt get overlooked by your desire to reinvent the wheel.
