I'm just downloading it now, having read a couple of reviews. I'm a bit worried to read that it's got some Broken Sword style crate-pushing puzzles - hasn't Charles Cecil got any new ideas? - but I'm looking forward to seeing what they do with it. It's probably a bit much to expect it to break any new ground in adventure gaming, but hopefully it'll be a bit of fun without being too challenging.
On a completely different note, as a UK license fee payer, I'm not really sure that the BBC should be spending their money in this way! Providing free computer games is not something a publicly funded broadcaster should be doing, as far as I'm concerned. However, I'd be even more unsure about it if they were allowing all and sundry to download it - sorry Johnny Foreigners.
