Power

Power tells a story about a Bitman who really wants to finish reading that book but for some reason the power went out. So he goes for a short adventure to the powerplant to restore the light and finish reading.

It's not long, nor it's beautiful, but it's far more than I expected  was possible for me in such timeframe. 

There is a fps setting in the game that lets you change internal clock and move faster but be careful monsters move faster too.
