Summertime Saga doesn't have a strictly linear development, you are free to visit any part of the city whenever you wish, and interact with all the characters you meet along the way. But only three events can be completed per day, after that you must go to sleep, starting a new day.
Your protagonist has a series of attributes which can be slowly improved as you participate in events. For example, improve your charisma by competing in rap battles, or your physical attributes by going to the gym.
One of the most interesting elements of Summertime Saga is, like most 'visual novels', you can develop romantic relationships with many of the characters. Learn more and more interesting details about the character's backstories as you get to know them better.
Go on an adventure with Summertime Saga! You'll enjoy the entertaining (and sometimes a bit risqué) story, numerous subplots, and strikingly good graphics.
