Why not sound?
I've come to realise how much sound adds to an animation - turn the sound off on even your favourite film and it won't be nearly as much fun.
In one sense, having audio allows for the opportunity to engage twice as many senses and so of course it'll be more enjoyable to watch.
But anyway, the animation was really nice. I liked the fluid splashing around and the excuse for rock-paper-scissors was amusing.
It could have been a bit shorter though, cutting some snippets here and there.
But brilliant animation. And for 2 nights - I applaud you.
