Ok so I played a decent chunk of the new update and I have to say that the new update was worth the wait.
This update has a lot of content (even if you exclude sandbox filler), the plot line and the way you encounter new characters is interesting, the couch tease scene was awesome, the gimmick of the story is being expanded on and isn't getting old.
What I and many people would like to see is the inclusion of the hint system (unless if you decide to bin the sandbox system, which I wouldn't miss seeing as I prefer VN type of games, with choices, a.k.a. what the game was prior to 0.3), also the CockCola girl should get included into the harem, hope the commercials were a teaser towards that. Other than that everything is going into the right direction and I'm not done with the update just yet.
However there is a unique opportunity that could arise from keeping the sandbox system and that would be to let us leave the apartment and to see how long it would take us for to get molested and to see if we could avoid it or willingly add new girls to the harem..etc.
EDIT : I'll probably write another update when I finish the update.
