How to update my game...? I have looked at these pages many times. please help.
i have no idea to get the new file. and overwrite it
Please see this post: https://itch.io/post/9984323! This post has details on where to go to download the file.
As for rewriting - simply drag the new file(s) into where you have the old file(s), and it should ask if you'd like to replace them (which you should say yes to) :).
