Escape The Hellevator! --- $2.99 > Free
Not sure if this is accidental or what, as I won a promo code for this yesterday at exactly the same time the whole world won promo codes (even if they don't know it). Still, this is in the Top 3 Escape the Room games, alongside The Room and Hellraid: The Escape. Really worth getting and, unfortunately, as neglected as a red-headed stepchild with a B.O. problem. Lock that license while you can.
