Decent idea, but the gun's unwillingness to target the only real threat makes it awfully frustrating. It becomes a long, slow grind for extra letters to transmute. Not worth playing for long.
Game is unplayably laggy even at lowest settings. This is a change from before update 1.002. Previously, I experienced periodic "warping" at the highest quality setting. It is much worse now, at the lowest quality setting.
For a game that seems to consist almost exclusively of combat, the pace of combat is far too slow. Grinding gets old, but slow-paced grinding is even worse.
