Defeat the Demon Dwelling in the Darkest Depths is a roguelike for Android. It features 9 different classes to play as, and dozens of dungeon floors to explore. Any loot you find along the way can be sold to the in-game shop or auctioned off for other players to purchase.
The game features optional permadeath. If your character is killed in a non-permadeath run, then they will resurrect with their stats intact, only losing some money and a couple of items which you can retrieve by returning to your grave on the floor that you died on.
I wrote a rogue-lite a few years back called Defeat the Demon Dwelling in the Darkest Depths. It's turned based and features optional permadeath.

You could try DDDDD. I haven't played much of it, but it might be close to what you are looking for.
