Putting a link to your itch.io page in the about section would be nice.
Remembering the language choice is also something to consider as do you really need to ask it every time? No, once is enough for most players.
This is somewhat dumb but for Ren'Py you need to add an extra _() to the input so it translates the prompts in other languages.
start.rpy
$ name = renpy.input(_("¿Como deseas llamarte?"))
translate english strings
# game/start.rpy:18
old "¿Como deseas llamarte?"
new "What do you want to be called?"
