Simple, but effective story tellling...
Well, all productions are complicated and time consuming, but i would like to have seen a bit more action. I.e., maybe have Donkey Kong synced to the music a little better.
The story idea for this short was good and the site gag worked, but a couple more frames in the animation (the one of you or your human subject) would help to further to get your audience to believe that he started out in 'reality' and because he had a drink (or earlier drinking) had caused the hallucination.
Still, a great use of minimalist technique and attempt to stay within the "beginning, middle and end" format of story telling.
