SANABI: The Revenant

Played another indie game worth mentioning recently, though this one has a large amount of reviews (34k), so must be fairly well known.

I wasn't really sold at first, but it has earned a place as one of the best I've finished this year!

You, a legendary retired veteran, are called upon for one last operation: to ascend a mega-city ruled by a corrupt conglomerate. You were chosen for this mission because of your signature chain-hook prosthetic arm and the ability to maneuver and quickly defeat enemies. The mission: to hunt down a mysterious entity known as “SANABI” and uncover corporate secrets hidden deep within the city.

Beautifully animated pixel art, plot heavy twists and thrilling gameplay... at least after you get the controls down! I'm a bit sad its already over, and wanted to add this to the "worth it", indie game forum.
Not perfect, but I find myself comparing every game I've played afterwards to it... so it's doing something right ;D
