Stunning visuals and amazing use of the title! The Memento flashback structure is well explained visually, and while I feel like I myself might have a hard time to pull it off, the module keeps it simple enough and gives enough material that I feel like I could try!
One thing that I’m not really sure how to feel about: If the players decide to do nothing each day, it seems like the module ends up the same way as if they were active in trying to interact and investigate each day. I feel like I’m missing something, but it doesn’t seem like there’s much leeway for future days’ information to impact the quality of the decision taken at the second day 0. At day 2 you will know the ship is attacked by the Eyes of the Void whether you take any action or not. I think I’d need to watch a playthrough to get a better idea of how player action affects the game experience and possible outcomes. Maybe this module is indeed intended more as a rollercoaster type of experience, and it is less about what players do and more about the discussions at the table. Maybe I have to go play this and come back yesterday to see if I get a better understanding of it.
