Just press space. Also it's a little bit glitchy sorry about that. Use arrow keys in part two If you get stuck in a wall just press and hold up arrow till your out of it then get out of it. I know this was a problem in level two. Yes I know the music that plays when you press space is really loud and obnoxious. If you don't like it press the 1 key, that'll turn it off. press 1 to unleash the shadow hand , press it again to stop
