Hey everyone, I'm the Developer of this game! I wanted to say hello and answer some questions you guys may have.
Some friendly suggestions:
Something like this would make <enter> keep the default name.
$ liam_name = renpy.input("You can change his name now.")
$ liam_name = liam_name.strip()
$ if not liam_name:
<tab> $ liam_name = "Liam"
Also, you could add code like this:
if renpy.has_label("patch_liam"):
<tab> jump patch_liam
else:
<tab> jump choiceliam
If someone were then to make a patch.rpy with those labels patch_liam and patch_landon, they could add some code similar to this:
label patch_liam:
$ laso_rel = "Son"
etc...
label patch_landon:
$ lifa_rel = "Dad"
etc...
