Boy, been a long time since i've been here but i felt that this might interest you guys.
I did a quick search and couldn't find anything about it (PISS turned out not to be such a great keyword), so sorry if it's already been discussed here.
So yeah, long story short: I stumbled upon this a few days ago on rockpapershotgun, tried it out this morning, and found it awesome.
I posted some more thoughts and relevant links on my crappy blog, and i'm too lazy to copy and paste it here, so go read that if you want, but be the important url is this one. Go there, grab it, play it. It's short, so you won't waste much time, and it's great.
Hope y'all enjoy it ;)
