Hi Sandpixie! Thank you for playing ^-^ You can check out the walkthrough if you have trouble with Julien, it's right here: https://itch.io/t/785875/walkthrough-spoiler-alert
About the twins, we cannot reveal what the endings will be, but what we can say is that the twins will have at least three different routes/endings, if not more - so there's a lot of room for possibilities :)
