Huh, I just played the entirety of Octodad (even better than I thought it'd be but too often on the brink of getting frustrated with the controls) and the tutorial and a few tries of Dungeon Souls (a lot of fun and I'll definitely play it some more sometime but it's probably too technical for me)
I think I should really at least try to play all those game I have in my Steam library, so I guess those are two off that list ^^
