Bored? stressed? give this game a try

/f/ has a core version of it, but this is the full thing with ambient music.

very intuitive game, watch 30 minutes to an hour slip past while wondering around.

you can also download the game to your computer from one of the mirrors on the site.

hints:
-red means down, blue means up
-the biggest 'part' on the body is the brain. eat that and the body dies.
-pentagon shaped parts with a + inside evolve the current section you're on at the time.
-orange = attacking
-white =neutral
-black = fleeing

i'm missing something important because i've been messing with this thing for the past half hour and getting nowhere. it seems that half the times that i try to eat something i grow, and the other half of the time i just die. if i'm lucky i can get up to four long before that happens. also, these 'blue' ones that bring you up don't seem blue, they're just small white dots. and i'm not seeing any of these orange or black ones that you mention. what the hell am i doing wrong?
