Locked In Edinburgh: The Secret Lab
The Secret Lab is, to put it simply, a brilliant game. I was left pretty much speechless for quarter of an hour after playing. It delivered a coherent set of puzzles that meshed beautifully with the story, forced you to criss-cross the space throughout the hour, made good use of technology and pitched itself at a perfect difficulty level. The satisfaction at having made your way across the expanse of puzzles was awesome. At the time of writing, this is my favourite game. Ever.
