Version 0.3 gets 4 stars in advance. Current state is 2.5 stars.
Version 0.485 gets certain 4 stars with a potential to get 5 if the development continues.
Version 0.84 still gets 4 stars, despite having plenty of content.
Apart from Engrish, the game seems to be a simplified version of GGGB.
This is not bad at all -- mainly because copied ideas of a good game are hard to spoil.
However, as of right now, there is not much content in v 0.3 -- only a few days and relationship scenes. The good thing is that you are NOT forced into any relationship.
There has been pretty much content since 0.485. Different encounters, different people. The relationships are rather straighforward, and may seem pretty boring, but it's more the matter of preference.
The main issue why the game doesn't deserve 5 stars is that the main character is forced with new content, and she automatically agrees to it, regardless of her stats or relations.
There are even such story-inconsistent events when the main character having great loving relationship with her boyfriend/girlfriend, is basically raped by acquaintances and even loves it as if she has never 'loved' her boyfriend. Or fucking herself with a 5inch-diameter dildo when she's satisfied with her boyfriend's size.
Luckily, sometimes you are given an option to select "No" when the content advances into a hot phase, but it's only sometimes.
Also, no visual lesbian content -- it is only implied, and may probably appear in future versions.
Lesbian path is finally implemented in 0.485
On the other hand, this is not a good 'lesbian path' when the main character automatically agrees on male strangers' sexual advances. Or there is no further development or drama scene when a lesbian girlfriend evidently cheats on the main character.
