This is a physics-based game in which you design your own tools to accomplish tasks and collect cogs (which help you accomplish more tasks). At first, I thought it might be difficult to understand, but there are hints, prompts, and do-overs along the way. Before long, I was really into it and had to force myself to get back to work! From Aardman Studios, the folks behind Wallace and Gromit. Link -Thanks, Evan Duval!
