Well, once you figure out the basic combat mechanics (which is easy--remember your first shooter? Fiddle with the controller for 5-10 minutes you'll get the hang of it eventually, just remember every weapon has its own moveset, but not really since most of them are copy pasta from similar weapons), and that upgrading your weapon to +5 immediately is your besty...in other words once you know what you're DOING its not all that challenging--cuz RPG see? Yes, Blight Town and Sen's Fortress, and the absurd number of random pitfalls/insta-kills in this game are bs but meh...that just means no matter how good you are you can still fuck up, and usually these things are because the player fucked up not because of "artificial difficulty."
Anyway...Bound by Flame is by the same French development studio behind DMC: DMC I think? Its a terrible game storywise and everything else, but the action is good apparently?? Lol, think The Darkness.
