First off, if you are a long time fan of dark souls, then you might "slightly" enjoy this game more, but Im not going to say that everyone who hates this game is a hater of dark souls.
The controls, as MANY people mentioned, are atrocious (bad), I died more due to the jumping controls than to enemies (at least it got one mechanic from dark souls right).
The idea for a good game is there though, the thing that people need to realize though is that this was never meant to be big, it only exist because people were complaining about how long dark souls 3 was taking to be shipped out. For a promotional game, for iOS mind you, its NOT horrible.
This was just a quick review: not a lot of detail. My final verdict of the game though is: a good game with spotty controls (AKA: an average iOS game).
