The Hunt for Souls
Another free ad supported game appears on the play store, this time in form of a 16-bit 2D platformer with on-screen controls, retro style design and it goes by the name of Olethros. Your primary goal is to find your wife and collect souls along the way.
Your wife gets kidnapped while you are being transported into some strange place. Fortunately you meet a talking bird that decides to join your quest and serve you as a weapon. On top of all you can’t remember a darn thing about your past, but you do know you have to collect souls through 66 levels and 6 boss fights.
The developer “PewPewNinjaX” has already announced the second and third part of the game in the description.
