Iuno which but I hope you will like them. Prepare for dying again and again.

Slay the spire is damn good, card game with a lot of depth and community mods. Been enjoying Heroes of Hammerwatch 2 recently, and of course there's hades which I thoroughly enjoyed

I know you are asking for a free rogueline, but Caves of Qud has to be one of the greatest games of all time. I don't know anything about this free version you are talking about, but the game is so epic, it is worth the sats.

Definitely Caves of Qud. I also recommend Tales of Maj'Eyal if you want something more old school (it also has a free version)
