Pathos NetHack (The OG Roguelike’s very newbie friendly fork and UI)
Rogue Saga (A simple, bare bones Roguelike, nice for a casual run)
Orna (If old school Final Fantasy were Pokemon Go, and didn’t have predatory monetization schemes) Heroes of Aethric is its non-GPS sibling.
Most of my free android games came from when Amazon did its Amazon Underground thing years ago, so you’re kinda SoL on that, sorry.
Very robust post, covered most of what I’d say in a far more verbose manner than I have the gumption for right now.
Kudos
