This game has to be the best rougelike for android that I've ever played.
I've been playing this game for years. And they keep updating the game with so many new contents.
Only downside I could think of are how some characters and part of the contents(like farming plots) are Pay to Play and also how the level generation does not have a large variety I normally expect from a rougelike game. But overall, this is such a great offline game to waste your time.
