Hmm, the style of the OP and that landing page reminded me of another web game I saw a few years ago with a philosophical theme, maybe a game jam entry? Kind of bothering me that I can't recall the name.
It was an abstract simulation of the course of a human life: units of "time" spawned regularly in the middle of a black screen. These gravitated towards the cursor and had to be guided to text spaced around the screen: play, grow, work, etc., which all needed to be regularly tended to, with more and more "responsibilities" appearing as time went on.
Some day there'll be an AI search engine for 'tip-of-my-tongue' media. But what will have grown faster? The ability to catalogue things in the world, or the depth of obscurity of things that can be catalogued?
