The changing scenery while you're circling a loop is a very interesting concept.
Gameplay-wise, it's challenging, but the ability to adjust your speed allows you to take risks at your own discretion. However, jumping feels very erratic and takes some getting used to. There's no shadow below you to give you feedback on how high you are during the jump. Ground collisions are also a bit awkward due to inaccuracy. I don't know if this is due to giving the player extra leeway. A brake button is appreciated ÒwÓ
