Definitely. I like it, I "finished" it over the weekend and got one of the endings, but I'm definitely going to go back at some point and get the rest of the endings.
It's an odd one though, I find it hard to convey my impressions of it.
Yeah, its a great concept and well implemented. Its an irony though that we gamers moan all the time that nobody is doing anything original and then when someone does we slate it. Its easy to see why so many devs just play it safe and rehash the same style of game over and over.
