About My Silly Science Summer in the Past

My Silly Science Summer in the Past - about the game

A cozy, time-traveling visual novel about friendship, curiosity, and weird science mishaps.

Take a trip back in time for the silliest, smartest summer you’ve ever had!
In My Silly Science Summer in the Past, you play as a curious and clever girl who stumbles into a strange experiment—and finds herself transported to the past! But don’t worry, you're not alone. Join a lovable crew of eccentric science girls: energetic Azuki, brilliant Marie, bold Patti, and mysterious Sylvia.

Together, you’ll explore bizarre inventions, solve quirky puzzles, and maybe accidentally explode a few things (for science!). Experience the power of new friendships, collaboration, and scientific wonder.

Features:
  • A heartwarming story about friendship and science

  • ️ Time-travel shenanigans with just a pinch of chaos

  • Fully illustrated characters and charming dialogue

  • Cool art style with cozy vibes

  • ‍ Four unique girls to bond with—no romance, just real friendship

  • A sweet narrative perfect in length for a relaxed weekend

Whether you love science, stories about friendship, or just a good laugh, My Silly Science Summer in the Past is your ticket to an unforgettable, geeky adventure.

Meet the girls! ‍

Azuki – The friendly girl with beautiful pink hair from the astronomy class that often starts telling scifi stories as if they were real. Is she just a bit weird or what's her deal?

Marie – The young girl from the country side. A math genius that seems to be awfully shy. Maybe she will become more talkative once she knows you better?

Patti – The cool physics girl. Experiments are her life, and wherever she does them she leaves a trail of fire and explosions behind. Her energy level is insane, but she would do anything for her friends.

Sylvia – "Baroness Sylvia von Tensberg", to be precise. Yes, a real noble woman, and totally not interested in science. She prefers arts. Why is she at the science camp then? Well, try to solve her mystery, but watch out for her sharp tongue!

Sweet Science

Parts of the game follow the story of our other visual novel "Sweet Science". This time, however, you are a girl who ends up at the mysterious science camp in the past. (If you prefer to play as a boy, try out "Sweet Science" instead.)
