All the games in Action 52 appear to be incomplete, still in their beta status. Some of them crash, most have bad collision detection, and many of them just appear to be incomplete. (e.g.: Non Human only has one level; some of the games have no music; the difficulty level is horribly unbalanced; some of the games glitch up when you complete the third level or so...) Apparently they've never heard of playtesting...
