Managed to miss this due to the hulabaloo that was Gamescom last week - Xbox Live Indie Games puzzler Blocks That Matter is now available on Windows PC and Mac OS, with a Linux version on that way too.

Imagine a platformer in which you can grab surrounding blocks, arrange them into Tetris-styled shapes and then climb all over them to reach otherwise out-of-reach platforms. This is the premise of Blocks That Matter, although it goes deeper than that, with blocks that have different characteristics and need to be tackled using varying methods. I found myself getting stuck quite frequently - it's a real head-scratcher.

Interested? It's pretty cheap, and if you like there's a demo to try out (well, apparently there is anyway according to the official site, although I don't seem to be able to find it right now. If anyone spots it, let me know!).
