Limbo was pretty fun. Its a completely black and white side scroller(like old school Mario with the pipes and the flags, but spooky as fuck) with random shit like 'OMG I'm going to drown' and 'the giant spider wears my corpse as a hood ornament now...' Its a puzzle game, I won't ruin the plot for you.

I think its like five bucks on Steam, worth every penny.

There's another one on the tip of my tongue, I forget what its called...

You really should check out the next project they put out called Inside. I thought it was miles ahead of Limbo.

That's the game I was trying to think of! They put in a bit of color, a bit of 3D, and they put in people. Probably one of the scariest things you might encounter on this planet are other people, and when they're doing paranormal shit things can get pretty nervewracking pretty fast, which they certainly did for me. I think the mermaid was the most anxiety inducing part of it all for me.
