I also was unfortunately unable to finish because of the black screen. :(
Some of the gameplay in this is a little TOO repetitive and without reason. For example, every time you leave, you have to speak with everyone. But their dialogue doesn't change and they don't even say anything interesting, just "we're waiting to leave," but in different ways. If you're going to force your player to talk to everyone before leaving, there should be a reason. Use that moment to give your characters some personality beyond just existing like they do now.
It's hard to keep a linear "groundhog day" like setup interesting, but small changes like that would make all the difference.
I wish your game / game dev well in the future! Thanks for sharing your game with us! :)
