I came in here and expected an interesting scenario and indeed I had one. For the simple game it is intended to be it entertained me for as long as it lasted. The stuff below would be part of the review but does contain spoilers so... if you don't wish to see them... you have been fairly warned

So when I played my first choice was to give her a chance to explain herself as well... life is fun. Even if she's a liar which she likely would be due to such a thing sounding quite... strange.... it still would be one of those entertaining encounters in life. If nothing else I would simply have a funny story to tell to people some time. So I heard her out. Now the critical point that makes this game solvable from the perspective of the player is that she says you will be rejected by the other girl, Rizette. Now what you can do and what I effectively DID do was I would confess to the girl anyway telling the girl as such: "You said that Rizette will reject me right? This seems like the perfect chance to see if you are telling the truth about being my girlfriend from the future as while much of the other stuff said to me could potentially be found otherwise, it would be very difficult to tell this with certainty. Thus if she rejects me you have been telling the truth, and I suppose I will have to believe your words." As such your character will go confess to Rizette. If I am not rejected (as occurs in the game) I will know her as a liar and continue with the girl my character appears to like most. If I am rejected I will end up believing she is speaking the truth but even if not, I would ultimately be happier as I would have a girlfriend that the character still appears to have some interest in. Thus no matter how the outcome goes, you can have the best of both worlds.

The actual story at the end though of what happened while not perfectly within my predictions of course was definitely an interesting twist though. While another poster said that more background information would have helped on all the characters, not having much knowledge of the girl from the future prior is obviously a major point to this game and so I can forgive that. However I WOULD have liked a little more knowledge on Rizette and my own character which is knowledge I should have (though my knowledge may be limited on Rizette, I must know SOME things about her or I would not have such a crush) and would have helped the decision making process. Overall though it is simple but a fun game. For what it is, 4 stars. The art style is fitting to the feeling of the visual novel though I might have liked more color and sounds. Overall though they are minor complaints and the game is quite good.
