Each matter has its specific behaviour, so you have to take advantage of them and use the blocks wisely. Get ready to use your brain and combine your platforming and puzzle-solving skills in this incredible mashup. This PND is a Launcher only, you'll need a full copy of Blocks That Matter to play it.
