Dungeon Crawl: Stone Soup. Free roguelike with lots of options, but uncomplicated. You can run it on just about anything. Source: almost 2 years ago

Also, Dungeon Crawl Stone Soup is a decent pick. It's free, so hard to beat the price. There's also no music or audio at all, which means I can listen to my own music or a podcast while I rampage through the dungeon as a Troll Berzerker, pulling apart goblins like they're made of monkey bread.

Dungeon Crawl: Stone Soup is a good one. It is a classic-style roguelike that does not feature sound effects or music of its own. I will frequently queue up podcasts to listen to while I take a run or two. Source: over 2 years ago

If you're down for an older-style roguelike, Dungeon Crawl: Stone Soup is free and it's optimal for a keyboard that has a 10-key (numpad) for movement. There is an endgame, but it takes a lot of luck and doing to reach it. I just poke at the game on occasion to see how far I get. Never been within any reasonable distance of the end.
