Hello!
Yep, for a while now. The GxB routes' writing will be finished by next month, which will only leave the GxG routes.
Wynn's route is definitely better with the third ending! I wouldn't worry about it, haha.
And actually, no one bought a third ending for Sho. It's not a full ending like Wynn's but a bonus bad ending that we thought fit easily enough into the game that it made sense to include (you'll see what I mean when you play, if you go for all of the endings). There's no CG for it, or anything. If we can find little extra endings to add to the other routes, we'll definitely do it, but they're not replacements for the main endings.
Thanks! I think we'll be okay now, since we're quickly approaching over 50% total completion.
