Oh man congratulations! I can't wait!
1) So far, I've played Sol and Rye's routes, and I love them sm aaa
One moment I liked in Sol's route was the options for what to wear at the beach. It felt really inclusive to me. I appreciate that a lot :) In Rye's route, I liked that we could share little moments with him in different places.
2) I would definitely stay on an island with Sol. The man knows both how to have fun on an island and how to survive on it, definitely >:O
3) I can't say whose route surprised me the most yet, so I'll just have to play some more :)!
