A simple module that gives the ability to autosave every 250, 500, 1000 or 2000 steps.
I haven't found another one and I've lost a few hours of game time myself several times due to lack of saves....
So there it is...
AutoSaver.zip
Wait, wait, wait...
You write that there will be a native version for MAC?
So then...
Is Linux... also hoping to be supported?
At least - if there is no other option - as clean code for self-compilation.
