I definitely was thinking of making a scrolling option for the pictures, but it could be very difficult and I'm not sure if it's even possible in RPG Maker. So far I haven't found a way to make that work yet, but I'm definitely on it.
Different variations of their pose is definitely a good idea, but would also take a lot more time and work, so if at all, that would be something I'd be adding way late into the game. I'll think about it, but I don't want to make any promises here yet!
dreamscapes themself will actually change up a bit sometimes, depending on which characters, so you're surely going to see different varíations of that anyway!
Thank you for your ideas once again!
