I felt the love that went into making this. Very creative approach to pretty much every aspect of the game, the theme, the music, the visuals all feel unique.
I got stuck at the bear too, although I might be missing something based on your reply to someone else below, cause I don't know how to attack. If I get close, it injures me, but nothing else happens.
I get your intentions about keeping it vague (the ability to observe and understand was key for humanity to get from there to where we are now, after all), but it's a fine line between enjoying something challenging or becoming frustrated by failure. Having to figure out pretty much all the game mechanics as part of the puzzle might be stretching it a bit too far, especially if it takes multiple seconds before an action is registered, and there's no feedback that what I'm doing is actually the right thing, I just gotta do it longer.
I hope you don't take this the wrong way, I'm super-impressed with your game, it's easily the most memorable one I've seen so far.
Special thanks for your long "post-mortem" on the game page, it was a really interesting read.
