First of all, I have played this game ver 0.0.08 bugfix 2.
Here are some of my comments:
Advantages of this game:
1) multiple type of girls with a slight different in personality, which might fit different liking of "player"
2) game system wise is fine with the logic of allowing the player to move around and does different action upon meeting girls on the island
Flaw of the game (as a gamer):
1) insufficient hints to new player, grinding is one problem, but after grinding lust, affection and love status of the girl, player will still get stuck and feel that there is nothing to play on. (E.g. next event or CG happens during which event, which time point etc)
2) Handphone event must be click at 7am exact or else you will miss out clicking agreeing to the event. Similar, events that ask player to meet at pool or room for example lacks time redendancy, if you missed that exact timing, you missed (Just a QOL issue, if possible, giving some time redandency like "if event is clicked between 7-8am, then XXX" instead of an exact "if event is clicked between 7am, then XXX")
3) Some girls can be progress further while some are still under developed (I have not completed the whole game as many event are still unlocked, nor have I tried to extract the CG file of this game to check which character have more CG). I think player will like to know which character can be progress further into the relationship in term of CG. Maybe some kind of relationship level to be explicit shown to the player? (I understand that there is a number indicator under the girls icon in the handphone menu which is helpful to some extend)
Overall, I liked the game. There are some bugs in the game but I don't think that is a big problem now as those can be fixed. The problem lays on the direction of the game play, making game play more fluid, and some interesting intersection of event between to make the story line more fulfilling.
