Castlevania: Symphony of the Night is a classic Metroidvania title from Konami. Its launch on the Play Store was a bit of a shock, especially since it's available for $3, which is a fantastic deal. SotN is a beautiful 2D platformer that offers non-linear platforming-based gameplay, so exploration is encouraged. The primary campaign should take around eight or nine hours to beat. Since this port supports physical controllers, it's a perfect title for this roundup. Don't sleep on this one. It's a classic for a reason.
