This is awesome! Movement feels great. It took me a little while to get used to the bike’s response - which is quite fast - but once I did it felt great, except for the bike rotating from one fixed point (i.e. like a unicycle, not a bicycle). Love the variety of moves you could pull off.
Falling off the tutorial level, and trying desperately to save it by bouncing back and forth between buildings, was almost as much fun as actually pulling it off - the hallmark of really buttery-smooth control schemes and sandboxes. 10/10
