This new falling block game from an indie developer called M.slivo that asks you the question: what if the blocks were made of sand (via Hacker News)?

Instead of rigidly fitting together, the blocks fall apart when they land, their pixels tumbling down the slopes. You clear “lines” by creating contiguous colored stripes that span the playfield. It breaks your brain in the most delightful way.

It’s for Windows and Linux only, unfortunately.
