For those who are new to VN/Dating Sim Games, by hovering your mouse to the bubbles on the side of your message box, you'll get something like this:
Skip - It skips text that you already read. CTRL is another alternative.
Auto - Pretty much, it auto shows the texts depending on the speed you set for it so that you don't have to click, click and click.
Stats - Shows the stats and money and the date.
Option - Allows you to set the speed, bgm volume, etc.
Save and Load VERY SELF EXPLANATORY.
Did you know that by doing a scroll up or down, you can "rollback" the game? and stops from where you left off? This is helpful if you accidentally missed a specific information 'w')b
