This is my favorite madness game. I like that it is turn based. I enjoy the constant character customization.
One issue with the game that is the backtracking bores me. I wander the empty halls, clicking the red arrow as soon as it spawns, and I do that 10 to 40 times. It's not worth lowering the 5 star rating though because it adds an element of cost to the items. In order to unlock those items all the way back at the start, it costs time.
My biggest issue though, would have to be the flashbang and the smokescreen. I do not enjoy that a lot of the harder fights can be done easily just by throwing a couple of smokes or a couple of flashbangs. These two items are too effective, and they take away from the game.
