I recently gave this VN/Game a try, and even though it doesn't have a deep story or completely plausible scenario, I was pleasantly surprised by it... The visuals are a form of 2D cell shaded anime style, with decent animations... It is your typical stat grinder with a time of day and location cycle... But not as grindy as most others using a similar format... The text is written fairly well... Overall, I enjoyed my play through... I posted my review with a more detailed insight...

Thanks for the detailed review. The only thing I disagree is about the quality of the text. My English is still very bad, and although there are rarely spelling mistakes, in compensation in many parts the text is very off and it is easily recognizable that I am not an English speaker.
This also explains why sometimes some characters communicate in a way that doesn't seem natural. As you said, the text of the game seems to have been written by someone very young, but this is because I never studied English in a formal way so my ability with this language must be comparable to that of a 10 year old child ... However, I don't mind that much because sometimes this effect makes the scenes funnier, and I like to create light games with humor.
Another detail that I found interesting in your review is about the lack of a story in the game. This is a conscious decision of mine, instead of telling a story in a linear and traditional way, I prefer to simply introduce charismatic characters and make the player learn more about them little by little. Often the characters don't have an arc where they will evolve as characters, they just "exist" and it's up to the player to discover more details about their personality and life (I think Megan is a good example).
However, in the case of Charlotte I will create a more traditional story where she and the protagonist will participate in a little adventure and she will experience things that will change her perception of the world and make her grow as a human being.
