For the next four days, Ubisoft's Child of Light will be available for free on PC through the publisher's Uplay platform, granting Windows users access to 2014 side-scrolling classic. From March 26th to March 30th, Ubisoft's Ghost Recon: Breakpoint will be available to play for free on PC, giving Ubisoft fans access to even more free PC content. This free period will be to celebrate the release of the game's 2.0 patch, which makes several major changes to the game and adds Vulkan support to the title's PC version. 

Child of Light is an RPG side-scroller that's inspired by several fairy tales. The game features turn-based combat, side-scrolling elements and RPG-like levelling elements and a crafting system. This game can be enjoyed in singleplayer and in a 2-player co-op mode.  To take advantage of these offers, PC gamers need to log onto Ubisoft's free Uplay service. 
 
Anytime I find a free game I am listing it for all of you. 

I really liked this game when I originally played it a few years ago. It really reminded me of some of the classic SNES RPG games I grew up playing but of course with much better graphics that lean to a children's water colored storybook look. As for the reviews on sites it's been generally well liked and on Steam it's got a community rating of very positive. I would highly recommend it as a free game. I don't regret it as a game I paid full price at release for which was like $19.99 or $14.99.
