This was a well done visual novel, especially for one created in a month's time.
I went in with little knowledge of the plot and the voice in her head serves as a satisfactory twist on the amnesiac premise.
The world building is sufficient. The clothes seemed funny to me, but it is the future after all.
The characters are where Mnemonic Devices really shines. They are likeable and entertaining. Despite not being entirely three-dimensional, they still act as unique characters not bound to the generic stereotypes anime-related media likes to perpetuate. This was especially surprising, given that this visual novel is an otome(?) game.
The choice structure is good. It is a primarily affection based system, with binary choices. There were many choices, but I like having a lot of choices, because then I can make choices based on my gut and let the plot lead me where it will, rather than having to follow a convoluted route guide, just because I gave tsundere-chan flowers on thursday rather than friday. What I most appreciate about the choices, were that they all within the context of the protagonist's personality, and largely reactive to how she feels about certain things. Too often in visual novels, choices lead to large swings in the character's personality.
I must say, this is the first visual novel to have player chosen names/appearance/pronouns that make sense within context. Too often they are used as thin attempts to have the player self-insert into the role of the protagonist, but as I said earlier, the protagonist's personality is already strong, their body doesn't really matter.
Good, if you like short romance novels.
