Came across this polished little Java game, which IMO belongs in the featured section.

[/td] [td]You are the Tetrobot: a tiny robot that can drill blocks of matter one by one, collect them, and recycle them into new pieces of 4 blocks. You also have the possibility to destroy lines of 8+ blocks in a very «retro russian» game style.
Sand, wood, stone, obsidian, iron, diamond: each matter has its specific behaviour you’ll have to use wisely and take advantage of them. So get ready to use your brain and combine your platforming and puzzle-solving skills in this incredible mashup!
