Maize (Steam key).

http://store.steampowered.com/app/284240/Maize/
Maize is a first-person adventure game about what happens when two scientists misinterpret a memo from the U.S. Government and create sentient corn. And that last sentence is pretty much the least ridiculous thing about the game.

Explore an abandoned farm and a not-so-abandoned underground research facility as you uncover the mysteries around Maize, and possibly learn a bit about yourself along the way. Or maybe not.

With a colourful cast of characters and an absolutely absurd world, Maize offers up a unique experience that keeps the surprises coming. Seriously, they’re everywhere.
