It was really hard to understand how and what I was supposed to do, but I think I got it, and I love the idea :D
So basically you are building your own tetris blocks, and then you have to drop them in the tetris grid. Then if you match certain blocks you get them back to build it again?
I think I would absolutely love this if I understood the rules, but after trying 4 games, I kinda gave up trying to understand it...
Great music though. Really cool mastering :D
