For any moment you read what you wrote? did you do any minimal research?, cause everything u sayed not correct,
the game is good, its made in rpg maker not renpy idk where you got that from,
its not a visual novel, its a rpg with stories, which you can play what content you want first and not a only 1 story with chance of go other paths to get more then one ending and in a visual novel you dont even play you only press 1 button,
city map design like SS/TT? have you ever played those games the maps not even near close to each other, the game already popular and it will grow more has future contents drop and the game dispite minimal problems that can be fixed its playable.
