At the time of writing this I have around 55 hours in the game and I still need to use the wiki on half of my runs. The game seed is randomized every time you play so the items and floors you get are all different from the last. Sometimes the game will gift you with great items and make it a breeze, while other times it'll dump trash on you and really make you work for it. The mechanics are simple and easy to get used to, but the game is still very challenging. I definitely recommend this game if you're looking for something to kill time with.
