Pros
Pro A variety of mods are available, which extend the gameplay by a large margin
There are multiple mods available that extend the gameplay or even just change it outright. This way there are many choices to the player as to how they would like the game to play.
Pro Tons of replayability thanks to the randomly generated level
In true roguelike fashion, levels are randomly generated each time a new game is started. On top of this mechanic, Pixel Dungeon goes one step further by randomizing effects of all items as well, so it's impossible to tell if a dropped item will have a positive or a negative effect based on its sprite representation.
Pro Challenging and fun gameplay that lends itself well to repeat plays
Pixel Dungeon's gameplay is intuitive, allowing for it to be easy to get into. What is great though is that it's also very challenging, quickly making the experience both rewarding and addictive. Just one more game is a thought many will have before actually turning off their device.
Pro Detail-oriented design lends itself well to many gameplay elements, giving a feeling of polish and care not normally found on mobile
Small details in the art design helps to add immersion to the gameplay.
Pro A good variation in items allows the player to constantly discover new and exciting ways to tackle the game
Next to the typical selection of buffs, de-buffs, potions (that can be either consumed or thrown), weapons and armor (the latter two have to identified and can carry with them bonuses and curses), there are also less common items like random teleportation scrolls, map reveals, etc.
Pro Easily play without an internet connection as the game can be played in-full offline
Pixel Dungeon does not require an internet connection to use, making for a good game to play when there is no internet to connect to such as on flights.
Pro Beautiful pixel artwork that should offer a good bit of nostalgia for anyone who grew up with games that look similar
This looks like one of the good SNES RPGs. For someone who grew up loving those games, that's a huge plus.
Pro Being completely free and open-source means that anyone can try the game in order to see if they like it
No advertisements, no in-game store, and available for free with the source code available on GitHub.
*There is a link in the game where users can donate money to the developer. This of course does not mean you have to, but it is marked as a game with in-app-purchased because of it.
Pro Has a reasonable amount of strategical depth where the player can easily plan out their next move
The top-down, turn-based nature of the game gives the opportunity to plan out a complex series of moves. This way there is no time constraint, and the player can leisurely strategize what they would like to do next.
Pro Hold your device as you like as the game can be played in portrait or landscape
Allowing the user to switch from portrait or landscape makes for an easy way to switch playstyles (one handed, two handed) depending on what device is being used (tablet, phone) as well as what is most comfortable for the user.
Pro Interestingly uses mind bending architecture in the gameplay
Players must figure out how to traverse the architecture in order to get items they need to use to help guide the the main character, who is sleepwalking. It is through this mind bending architecture that the core of the gameplay lies as each level is a puzzle in and of itself to figure out how to gain all the items needed, which is only half the gameplay as once that is figured out they then need to guide the sleepwalker to their goal.
Pro Excellent sound design
From its background music to its voice work, the sound design of The Room Two not only fits with the theme but adds to the player's immersion in the game and overall experience.
Pro Surreal graphics
The graphics of Back to Bed are very surreal, as if Dahli and Escher had teamed up to design a game.
Cons
Con Pixel Dungeon is hard
Pixel Dungeon's difficulty can be a turn off for some players as it is quite challenging. While there will be those that enjoy such difficulty, those looking for something easy may not enjoy the game.

Con Overly random
A lot of people see roguelike design as being based around randomness. It's actually a far more precise set of balances than that. A lot of roguelike developers shy way from "randomly generated content" in favor of the term "procedurally generated content." The reason for this is that a well designed roguelike is well balanced enough that if you lose or win, it's all because of the actions you took.
Pixel Dungeon has a habit of sometimes generating dungeons that are basically impossible and sometimes generating dungeons that are laughably easy.
Con Randomness cannot be turned off
Since everything in Pixel Dungeon is randomized, sometimes a player's character can get killed in ways that cannot be avoided. There is no way to escape this issue since randomization is baked in with no way to turn it off.
Con Puzzles could be deeper
With such an amazing graphic design, the level of depth to the puzzles feels almost disappointing.
