Got some spare Microsoft Points lying around? Take 240 of them, and go purchase Blocks That Matter, a new puzzle-platformer from Swing Swing Submarine that builds on the concept the dev previously used in Tuper Tario Tros. In each level, you need to collect bricks together, then use them to build bridges and stairways to freedom.

However, you can only place the blocks in groups of four, in the shape of Tetris blocks. Each type of block has its own characteristics - some fall when there's nothing below them, while others can't be drilled at all. It's pretty challenging stuff, that will test your brain over 50+ levels.

Definitely worth picking up - give it a download from the Xbox Marketplace, or grab the demo to check it out first.
