Thank you so much for this incredible comment. I appreciate all feedback and I love that you loved this game. It's been my passion project these last few years.
Your order is pretty much the order I recommend anyway, though there are pieces of the puzzle answered in each route so it wouldn't matter too much if it was played out of order.
BTW did you find the second Felix route? Atlas has a poly route, where you can romance Felix as well, but there's another Felix route that goes into the war rebellion. You can find it by choosing Alasdair to save you from the prison and then picking choices that favour Felix over Alasdair.
And thanks for letting me know about the bug, I'll fix it in a future update.
