The info ap is probably more coding than anything for megalono at this point and the reason for it needing to wait for the other quests to complete so the info from those go into it.Thanks for this satirious . Was hoping for a Simple Christmas but fingers crossed for a New Years surprise!
While I'm bias since I'm a fan, I would postpone the "New Requests from Girls" and the "Info/App" upgrade until the version with the mansion if I were the dev.
First, thematically, getting the mansion at the same time as more info on the girls is a nice Life Progression bonus for current players. That it applies backwards to Day 1 is irrelevant to people with max grind (or console cheesed) play saves who will probably move into mansion as their first pre-workday/post-workday activity. "New Year, New Me" as the saying goes.
Second, the "New Requests from Girls" will probably spark new creativity from the dev when the MC and girls are in a house. Mow the lawn, wash the car, clean the pool, et cetera. Flows naturally with the new location otherwise he's going to be working on "New Requests from Girls" twice, for pre-mansion and post-mansion.
Finishing the Sasha animation - which is enjoyable for the dev - and then the Oliver/Julia story content which is essential to the code base, is far more important than the above IMHO.
If I am correct, then delaying it until the mansion would be counter productive. He needs to get that info ap in the wild so it can be tested and broken by users ahead of adding the mansion code. That too will need to be beaten and broken by users. Releasing them together will muddy the waters in testing and repairing. That is something none us that enjoy the game want.
Bugs suck for everyone. Bugs that are difficult to narrow down because of two major code additions on top of themselves would suck more.
