Simple but cool

That was nice! The animation was pretty good, better and arguably more original and enjoyable than the last thing I saw from you.
The story was pretty archetypal "main character wants something, main character tries to get it, main character fails comically", but still done well. These types of goofy cartoons can be fun. I liked the motivation here. Docoin's personality is fairly interesting and it's nice to see him get repaid for his selfishness in the end. I really liked the twist toward the end, when the blocks started falling in real life. Guess you shouldn't kick Tetris levers. Nice ending, too.
Keep it up, this was an entertaining watch. Just gotta keep practising your animation now and you'll be doing just peachy! Maybe don't use so many squishy sound effects though.
