I loved the game! Nice puzzle and super rewarding animations and sounds. And of course, being able to be told that I'm a Tetriverse master!
Some levels I had to play them multiple times to learn which peaces where part of the total set of the level. I got stuck a lot in level 8(And I have the feeling that I just got it right by trying a bit randomly) and a bit in level 9. Level 10 was much easier.
