Sparta?
Ah yes, I really should have seen King Leonadias (or however his name is spelled) emerge from this sooner or later. He was easily the coolest thing in this cartoon. At first I thought it was going to be a more generic Tetris parody. That still didn't make it something I would recommend, though. For one, it's a loop, which I guess isn't your fault considering the problems some people have to work through. It was weird how the same scene happened twice.
At least the Tetris graphics were fairly decent in their own right. Of course, I imagine it would not be that difficult. Next time, I suggest that you make the action move faster, especially with the king. You could also work on a more original song. It makes you realize why Tetris is so popular in how simple its design is.
