Not a particularly great animation
This animation was sort of a let down. There was tons of build up, and I was expecting a fairly hilarious conclusion. Instead, it was simple toilet humor, and I was left disappointed.
Your artwork is good, and the animation flowed well enough. However, what really is lacking is the humor. I was expecting some subversion of a gameplay element or something along those lines. Instead, you simply used toilet humor to elicit a laugh. However, I don't honestly believe that many people would find it all that humorous.
So, in terms of art, I score highly. However, it is the writing that falls short. I think it would be best that you work on writing, as you have a well-developed art style. You just need a good story to back it up.
I hope you don't take my review too harshly. Just keep working at it.
