So saw that some people have problems as they want to download the game instead of playing in browser and as I got the game to work thought I'd share what I did(mac used but might work on others too):
Firstly I dowloaded the game through the itch.io app as otherwise I could not even get the game to open. (64 bit version)
Second I changed the setting before starting a new game. It seems the text is too quick so maxed that out in seconds as you can just click if you want the text quicker and turned off the marked things in the skip section.
Before I did this game would close or I'd get the black screen a lot of people seem to talk about. This ofc don't fully fix it. it can still close if I'm too quick with clicking over text and I don't try to skip anything as I know it is a bit temperamental. BUT it does make the game playable. Stick to the same rules as the web version with not having too many save slots too.
As said it does not fix the game a 100% but it has made it so I can play it with the least amount of issues, so thought I'd mention it. It really is a lovely story and universe <3 so hope people give it a chance
