Via the means of shape-shifting, Tetras can turn into different Tetrominos and used to fill holes and master puzzles, in an attempt to reach the portal on the other side of the level. But, don't just go expecting a linear adventure, as sometimes crafting a staircase to the heavens is the only way to make it to the end, so if you dare to dream big and go block mad, you might just have what it takes to bring all the Tetra’s back home!
