I can't exactly tell if this is made with 2D or 3D, which is a plus because that's kind of the feeling of the original. Trees seem to clip into the camera which makes me suspect 3d, but all the trees in your view seem to move on a direct vector towards the player, even if they are very far to the right, which is kind of disorienting because that's not how a 3D space would work (which is why I think it might possibly be in 2D).
