hi there, being in top 3 in someone's list is always great ^^
As for your questions:
1. I'm working on this vn alone so it really depends on how fast I compose the script and make the art, but it should receive an update at least once every 2-3 months as long as the support continues here or on Patreon.
2. Not very likely, it's not a bad idea, and if it turns out to be easier to make than it seems, then maybe, and I mean a BIG maybe.
3. I can't say who will be next, but on my Patreon there is a poll that ends in a couple of days to vote on the next path, if you want to give Tate a better chance, consider voting there ;)
