Gave this game a couple of plays and unfortunately I didn't enjoy it that much. It feels like the bat's inertia is too high, especially compared to the pedestrians who can do sharp 90 degree turns, you can keep flapping wings but you'll either lose speed or fly into a building. The physics in general are strange, cause I'd expect the bat to fly down faster due to the gravity, but it doesn't happen, gliding doesn't work, either.
The furthest I got was level 6, I think.
