@Pandimo: No, it's a reference to a physics problem, where (IIRC), the essence of the problem is that calculating the motion of bodies in space becomes nearly infinitely complex beyond two bodies, hence the 'three body problem'.
Haven't played the game yet, haven't even looked at anything beyond the loading screen, but I'm going to take a WILD guess as to what happens:
It'll be one of 3 things:
1. The dog dies
2. The boy dies
3. They're both already dead and are just ghosts in the process of figuring it out.
Because True Art is Angsty.

This is a really fun, and brilliant game. The cumulative effort effect is a brilliant way of forcing players to optimize and making our decisions matter. A larger game built on that base principle would be revolutionary, honestly.
I don't think it's fair to exclude Internet Explorer users from games. I know it wasn't done intentionally, that it was a property of how you coded it and what you wanted it to do... but it's still a decision that feeds the egos of elitists and asshat browser hipsters, and it's not something I like.
Honestly, this is an amazing game. I understand it's an enormous labor, but I can't help but be impatient for your next game; your games are universally well-designed and well thought out, and fun.
