I tried for a while, and got to the level that looks sort of like a space invaders alien, but the controls are really weird. When I'm jumping off of a wall, sometimes I just do a small vertical jump and climb a bit, and sometimes it's a big jump away from the wall, and I haven't figured out when each kind of wall-jump happens, so I've just been kind of hoping that the right one does. Also, the right half of the controller is responsible for jumping, sprinting, sliding, and climbing, but all that the left side is used for is controlling whether you're going left or right. I would've preferred to have one of either sprinting or climbing be attached to the left trigger instead of both being the right trigger/bumper. Or, both triggers could've been sprint, and both bumpers could've been grab.
