What a lovely game. Possibly the first one I've 100% completed, I don't recall another, but it wasn't very hard to do it. It did have some framerate issues and some people may find it too easy and short, but they're probably missing the point and rushing through it. I must have put around 10 hours into it and I'm happy to pay the £9 for this gentle and amusing puzzler.
Stacking: The Lost Hobo King DLC is now available. £3.19 on the PS3, more on the 360 by the look of it. I'm getting the impression it's very short, but hopefully not too brief. I'm just happy for more Stacking.
