Heyo!
1. Stats are very old and don't have any use in todays version, however we do plan to add some stat grinding for you to develop your character and open up some routes (like physique for Zahera or charisma for Ava, y'know?).
2. Game's intro is probably as outdated as stats and will be completely remade. We plan to do a main story that takes a pause after the intro to let you free roam and do whatever you want but after you decide to proceed you will be able to finish the game and (MAYBE) even get different endings depending on who you befriended.
3. Not sure since some of the NPCs will be remade slowly as we update our backgrounds and rework/add NPCs. Probably she will just a get a glow up and maybe a little scene, but not a route like the main cast.
All good about the questions, and you are somewhat correct about the whole "don't know how the story will end" but it's mostly because when we started we had no idea it will turn into such a long-lasting project that we would have to actually start updating old stuff. So the story there was alright for the scope we were aiming for at the time. Now we're dreaming big so the game will have to keep up with our insane new ideas.
And yeah, our programmer is getting better. Doctor said he has pneumonia, but it's very managable. I sent him all the comments people left that wished him well, and his heart melted away lol.
