Well, even though I did like this game, I find Mr. Pig's Great Escape to be superior in design: the challenge is clearer, design is more mindful, and even though it is harder it is less frustrating, thanks to the lack of a life system. The overall game, in my opinion, is better executed. However, that's understandable, since this game is much more ambitious, with it's open levels and environments, so I wouldn't say Mr Pig is necessarily a better game. Though the art is better here, the visual feedback can be really terrible at times. Distinguishing between foreground and background is a pain, but that can be fixed with a simple tint in the tile art. Also, given the size of the levels, restarting can be a bit annoying at times, and since it is no easy game, losing all your lives and having to restart the whole thing is even worse. I would rather have losing a life send you to a checkpoint, and losing all of them to the beginning of the level, or perhaps ditch the life system, but all of this would require a whole level redesign.
This game has a lot of potential, which I hope is fully unleashed for the desktop version. Best of lucks for that!
