Played the hell out of the demo. Got the full game and so far it is brilliant!

OK, you block bullets with the bike, reload your parry with a front flip, and reload your gun with a backflip.

And I was addicted to whatever the first bike game that did this was back in the day, so exploring a map with it is really fun so far.

Edit: it doesn't force you to, but if you choose to sprint through levels holy hell it plays fast.
