This game is simply amazing.

You start by choosing a class and up to 5 perks, but you will have to unlock most of these first.
It's fun trying different combinations and seeing how they play out.

The map is determined by the seed you choose, you can pick a random one, enter one yourself or choose one of a few daily dimensions that are altered in a special way.
The game is rogue-like and turn-based, dying means perma-death.
During your run you will explore the map, find loot, kill monsters and other enemies, level up, talk to several NPCs who offer various services, recruit NPCs to help you fight and finish your main quest (which is usually killing a boss).

Every turn the darkness behind you consumes a little bit more of the map, so you have to keep progressing forward and think carefully about if you'll have enough time to explore a dungeon or visit a town. Normally this isn't really a problem, you can easily outrun the slowly-progressing darkness.
In case of emergency you can use your Awakening ability up to 5 times, which stops the time for 3 turns so you can get yourself out of trouble.

Usually whenever you die, it is because you weren't careful, you will learn from most deaths.
Most of the time there are ways to save yourself, but you just didn't try or think of everything or were too cocky, though of course there are also times when the game really seems to hate you.

There are multiple endings depending on how you beat the game and which NPC you have with you.
Moreover when you beat the game you can store some items in your vault, which you can choose to use at the beginning of each run.

Lastly, it's a single-player game, but while playing the game online it will show you details about other players who are in the same dimension and occasionally you will meet ghosts of other fallen players who will drop one of their items and give you experience.
Furthermore after clearing a dimension it will show you the characters of everyone who completed it as well.

For the price, especially when it's on sale, it's a steal.
I definitely also recommend buying OWH+ if you already enjoyed the base game, it adds a lot of new content.
