Okay, I just finished playing this on Steam. It's pretty much everything I wanted from a game right now... and even though I know there's a third ending I haven't seen, I don't think I can bring myself to reset the game and try the third ending.
I don't want to say any more because spoilers are a big thing here, but this game is amazing. If The Stanley Parable can be compared to the writings of Neil Gaiman, then I'd have to say that Undertale would be the equivalent to Terry Pratchett. Also, it's a JRPG as opposed to the Stanley Parable being a point and click adventure with an FPS engine.
