Fishing Paradiso by Odencat -- a fishing RPG with melodramatic backstories and a weird and wonky theology that still manages to reel you in.

From a game design perspective, this is a fine example of how to set up progression, all done at various levels -- the abilities, the opponents, the character stories, and the location reveals. Not too difficult in game mechanics but does take time to complete. From Google Play.

Caution / spoilers: some stories touch on death and suicide, and there are some creepy visuals and characters. Be aware when letting kids play, as you may need to give them some guidance.
