Thank you very much for your comment!
I'm glad you enjoyed the game. You're right, there aren't that many things to do differently in the game, but there are a few different endings that explain a bit more.
If I had more time I would've made many more branching paths, but unfortunately there was a deadline to finish the game.
Thanks for telling me about that bug, it's definitely not intended to be able to re-arrive at the same location. I'm currently doing some minor behind the scenes improvements and I'll fix that bug as well and upload a new version in the future.
