The collaborative cover album reinterprets the soundtrack from developer Swing Swing Submarine's puzzle-platformer. Music is composed by Yann van der Cruyssen, aka Morusque. Participating musicians have contributed to an assortment of independently developed titles, from Fez and Squids to Big Bang Mini.
The nine arrangements featured on the compilation are by Z.E.P., Romain Gauthier, Clément Duquesne, Sylvain Hellio, Yann Cleophas, Guilhem Cleophas, Dj Mokram, Souleye, Square tune magician, and Disasterpeace.
Blocks That Matter is available for Windows, Mac and Linux on Steam and GOG.com. The Original Soundtrack is also available on Bandcamp.
From the product page:
When indie game developers Alexey and Markus are in trouble, their only hope comes from their creation. 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!GOG - Blocks That Matter
