I appreciate the kind words! Doing my best to write from a progressive mindset (i.e. one which is positive about diversity) is important to me, so I'm grateful for the feedback! And as a side note, I am trans myself. :)
About the saves:
(I'm assuming you're on Windows)
At least when moving saves from 0.4.6 to 0.5.2, you should be able to just transfer the entire "save" folder directly into the new version. :)
Thanks for playing!
I'll keep working hard on Transportal! ♥
