World of Goo
The good old World of Goo has been remastered (whatever that means) and is now being released under Netflix in the App Store and Google Play.
That is, the game is free, but you can only play it if you have an active subscription to Netflix.
I'm not sure how to react to this, but the game is cool. I used to get hooked on it back in 2008-2009 instead of preparing for exams.
