I'm also having issues with Windows, it was stuck on the second scene for me. Hopefully you can get it fixed.

I'm sorry, that's because there's no more content, the game ends here.
In order to "fix it", I need wayyy more time, making a game with a lot of content is so much time consuming. It's the second time I make a narrative game and I think the biggest issue in this kind of game is the lack of time.
I made a model for the spaceship, but It's unused at the moment but still present in the source files (within the store.blend file).
Also I didn't find much time to make it, it's the result of almost 20h of work.
