Pretty cool
Always nice to see some backstory, but it wasn't very explanatory. Why were the machines taking people and sealing them in tubes? Why did they release the nameless protagonist and no one else? This just makes me want to see Tetris'd 4, for some kind of explanation, or possibly Our Hero freeing his people from their mechanical captors, since all he really did was destroy a Tetris factory in the end. T'would be nice to see a better conclusion to the series than just him riding off into space and escaping everything; he managed to fight the machines so well, he could be a savior for the people.
