"Kind of like Sierra PC-era meets Christopher Nolan sci-fi."
That's how I described The Silent Age: Episode 1, available for iOS and Android, in an email to a friend of mine. Admittedly, I specifically picked two references I knew would pique his interest, but it's a pretty apt description. This game has got the nostalgia factor of the classic point-and-click adventure, and an awesome retrofuturistic creepy atmosphere.
Even better, the creators made Episode 1 free (really: no ads, no need to buy in-app currency, nothing), and are relying on crowdfunding to finance the next version. Because they know it's that good.
It really is that good.
