The game is made in RPGMaker and with the way RPGmaker is, the menu screen is inaccessible basically during the entire gameplay (because the whole thing is basically cutscenes and the menu cannot be accessed by the player during cutscenes) and saves have to be manually put into the code at certain places to allow the player to save. All of our future VNs will be made with Renpy so we don't have this problem anymore :,)
