Hi Eeupy!
Thank you again so much for your thorough and thoughtful review. Thanks to your screenshot I was able to correct that offending v_rooted = Fals typo. I've gone ahead and made some color alteration that will hopefully make the glove easier to find. Some of the other issues you mentioned, I will give a bit more time to consider fully.
As far as the boss encounter is concerned: The boss choices are related to which vassal is summoned. ATM Seladre is not implemented so all answers lead to Reith. This will be corrected in the future.
It is not possible in either Soul Union or Soul Labyrinth to get your vassal to hate you, (except in very, specific deal breaking question in Simion's and Grei's routes that were not implemented in current version). The ritual lore makes it very difficult for vassals to hate or even fully challenge their weavers, which is why I plan to make interactions take place inside and outside of the ritual in this sequel. Ultimately these games are more about "bonding" and what kind of bond is created, than "liking/hating" by answering questions a certain way, so there are very few instances of making a definitively "wrong" choice.
Your concerns about the characters, their lack of appeal, or development are totally valid and I hear you. I do plan on having a lot of personal growth for both of them in the future but they may not end up being to your preferences. I hope by having other options available that you may end up having a good experience with some combination of characters but I can only keep trying and being mindful.
Thank you again so much for your thoughts. <3
