Im starting to feel like alice down the rabbit hole now, lol. 3rd stage is a bit eerie - i like it. Im not sure how to put this - but i felt at the end of stage 2 that my conversation with the narrator wasnt over yet. When you start stage 3 its like a completely new topic, could be a smoother transition.
The mysterious atmosphere is enough to keep wanting to see the next stage, but the controls need work. What i would like to see is - when you go down a hill your speed shouldnt be capped, you should increase speed the same way a real wheel would.
The flying is cool for the part where you interact with the eye - but at all other times its a bit frustrating for me.
