I don't think the story is that interesting. The minigames could be cool but the flashing and static makes it difficult to tell whats going on and is annoying.
Big issue is the auto feature. Whenever you have to type a message you have to click on the screen (even if you;re not choosing from multiple options). I've never seen another game do that and for good reason.

Having the entire game be told by text messages sounds interesting but it's not done well. Just seems worse than if you used VN Maker. I don't think this game is worth buying. I see potential if the developer is planning on making a new game
