I actually enjoy retro gaming. Earthbound and mother 3 are my favorite games! The professor Layton serie is also great! The thing is, while retro games are a huge source of "free" games, they're often too hard. I also found myself falling in a rabbit hole with an entire generation of retro games that nobody cares about anymore despite being full of great games : flip phone java games" (j2me). I highly recommend trying them if you want to play games on your phone without being thrown a billion ad and microtransactions. Just play the touchscreen variants and your golden. Some good games are : doom RPG 2 and Wolfenstein RPG, literally any game by digital chocolate.

thanks a lot for recommandation, sea of stars and pizza tower look 👌! and yeah my machine isn't capable to run bigger 3d games. Lol.
