Nitpick, but I hate it when devs - even devs making tiny weird experimental games like this one - feel compelled to add some objective, any objective, into an otherwise open-ended experience. Even if it's optional, it's lurking there like an unnecessary specter, ruining the freeness of the experience.
Edit: This came off as more negative than I wanted it to. I would never discourage someone from exercising their creativity, and creativity (and craftsmanship) clearly went into this. I was just using it as a jumping-off point for a broader discussion about something I see as holding back game design as a whole, which I better articulated here: https://news.ycombinator.com/item?id=25995867
