Thank you so much for your feedback. You unlock the time skipping, character/quest log and girls log icons/functions later in the game(after the last scene on this version). I just wanted to add something like "mini tutorials" at the beggining of the gameplay. Eventually (maybe in one or two versions) the game will have all of the content from previous versions(rainy days/H events/all of the locations) but you will need to unlock these functions so they will make more sense and will have a lot more content.
I'll try to make it more simple and straight forward from now.
