Well, I didn't want to waste clusters on the air dashes since I don't use them, so I encountered a small bug. When you glide, it's almost perfect flight. However, when you drop then glide again, it bounces you back up to where you originally stopped gliding, but it's not a hard stop so the speed you gain to get back up there raises you further each drop. This gets hectic as when you stop gliding and begin, it LAUNCHES you up to the ceiling quite easily. It's not game breaking by any means, just a bit of a bother. Also, sprint 4 is extremely hectic with tornado, just a heads up. The cars and civilians barely load and everything just explodes. Maybe it's because I have the gain max sprint speed faster upgrade, but for the time being I haven't bought it again after testing it. Other than that, jump 4 and glide 2 are aces.
