Alright: the good news is that this is a very well made hack and slash action/adventure game. The story is simple yet well executed, the lead character is engaging (at least what we see of him in the nicely illustrated comic-book intro) the animation is generally good, the environments well rendered, framerate and controls are excellent.
The bad news is that this is quite literally a prologue: the whole thing can be completed in 20-30 minutes, with only three types of enemies and little variety to the combat. The fact that it's free takes some of the sting from the lack of content.
There are a couple of non-consumable IAPs, each for .99 -- I ended up buying both to throw some money at the obviously well intentioned devs.
Seems like this is the work of a Turkish team, which is great -- we need more game developers from outside the North America/Europe/East Asia triangle.
