I am super into this game, but it is DEFINITELY not for a casual player. Out of 40 floors, I've spent 80+ hours getting to floor 33. The grind is insane, and little mistakes can lead to hours of farming, but if you are into games like this it's a blast. The soundtrack is awesome and the gameplay is challenging. The game can offer a good 10-15 hours of fun without getting into the heavy grind of it, so if that's your style go for it lol. I recommend giving this game a chance since it's free-to-play and entertaining.
