Shattered Pixel Dungeon the most active fork of pixel dungeon, a rogue like dungeon crawler:

Pros: Simply fun

Polished AF

Has a lot of well balanced items, enemies and unique classes/sub-classes (giving it infinite replayability) actively updated

Also has a lot of great and unique forks (commonly called “Mods” by the community) such as Rat King Adventure

Has good support for both PC and phones (I also think it works well with controllers)

Cons:

You will die

You will die a lot (don’t worry, it’s worth the pain)
