I absolutely adore this game! After downloading the latest update the day before yesterday, I couldn't wait to dive in after work yesterday to explore all the new content.
First, regarding the unchangeable elements:
- If you choose to share Emma but then proceed to arrest Mario, Emma will still hold a grudge against you and cease any meaningful communication. After arresting Mario, if you immediately visit Soria at the gas station and accidentally select the wrong reward option, Soria will continue appearing at the bar on Wednesdays and the gas station on Fridays without any possibility of unlocking her romance route. Reporting Soria leads to her irreversible downfall while simultaneously locking you out of arresting Mario. This seems to be the developers' way of forcing a choice: either unlock the guest room with Soria's corruption, or arrest Mario without accessing the guest room. (I really wish there was a way to enjoy both Soria and Emma together at Mario's mansion.)
- Most importantly - Anna (of course!). If you don't choose to share Anna with either Joseph or Adrian, your Thursday movie nights won't progress beyond superficial interactions, even secretly. After Anna becomes promiscuous, the kitchen interactions don't offer more options compared to version 1.5C. Her outfits remain limited to basic clothing or just a bra with apron - no customization available.
- Festival issues: For Joseph and Adrian's birthdays (possibly due to my choice not to share Anna?), the celebration is limited to giving basic greetings in their respective rooms (office or Adrian's bedroom) without further interaction. During the anniversary event, I triggered a scene where Joseph mentioned meeting in the garage, but he never appeared there despite multiple attempts to reset the trigger by exiting/re-entering. As for the Easter egg hunt, I collected 3-4 eggs but no special event triggered that night - I wonder if other players have had better luck collecting them all?
