Okay... So let's me start by saying that as of 0.47 this game is huuuuuge... More than one year of in game time, wich means way more than 20 hours of real time efficient gameplay. And it doesn't feel long, because it is well written.
There are more than one part where i chuckled, cause it's funny, but it doesn't get goofy like some other VN do. Well the self proclaimed best warrior of the island gets pretty close on occasions though. The story is good, animation is rather smooth, and some characters are cute - team Scarlett all the way, although Alice is quite something too, before she turns from enamored sub to fanatic.
I quite like how Sarah evolves too in opposition as to how Daisy and Nadia seem to just hold back their natural tendencies. Then again Sarah's arc is older and she may have been in a similar state of mind at first. So yeah there is a certain depth to - most of - the characters, so kuddos for that too.
There are a couple plot holes -waiting days for Nadia to fix the boat while "you" could just turn it back to new- and some light glitches -most annoying one had some text from a, long passed, one time encounter appear through part of the late game- But overall the game is of great quality.
Maybe rethink some of the market system/upgrades for the hotel. Because at first it feels a bit grindy and later you make more in a week than you need in a month. Or think of ways to spend it - gifts, ransoms, ... or the trip to Paris wich is supposed to be a secret and could require discreet funding. I mean i have around 500k laying there for no reason, paid for all toys and all upgrades at the current end of the story. Maybe dissociate the hotel funds and the salary of the MC?
