Summer Crush

Summer Crush is a visual novel for adults where you have to get into the role of a young man who has just graduated from high school and is about to go to university. The last summer of your childhood would have passed you by, but you agree to go to a random party, and after that your whole life changes completely. Now it's up to you to make sense of what happened and untangle the tangle of a story full of fun, girls, and, of course, sex.
