Some of the art is very good. You have made good use of filters. All is at least OK. The idea is fun. The animation is not very exciting or technical, but its OK.

needs a proper credit to the makers of Tetris within the movie. Maybe the ghosts (are they dead yet?) of Garasimov and the other guy should come into future episodes. PM me.
Really, this one owes its success to the enduring and captivating popularity of Tetris more than anything else, but the choice of subject matter is all part of our skill, isn't it!
