About

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.
🌸 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.

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!
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.)

A very nice visual novel. It may not be required if you already have Sweet Science, but if not, then this is well worth getting, and even if you do, the different perspective changes the orginal story somewhat. Lovely graphics and music as usual The English is a bit stilted in places, but it's not too bad
Nice music, and a lot of love put into the game. It has this quirky little feature that explains to players non-story related information, and choices where you have to know your "intellectual" stuff, like Maths or Physics. Though, it would've been good if the game didn't let you scroll back after these choices. It also has mini-games, which so far, haven't been a hassle to complete. I've not played it all yet, but I think I'm going carry on just to see how Sylvia, a snobby noble develops as a character, because she seems like an interesting character.

A very nicely made visual novel. It's the "companion piece" to Sweet Science in which you can play the scenario as a girl and - as far as I have seen yet - without the romantic aspects. So you can play it as a new take on the story but it also stands very well for it's own. It's a fun, entertaining and well written science fiction story with endearing characters, solid production values and - for those who remember - a lot of nostalgic and nerdy elements from the Nineties. I highly recommend it!
The Sweet Science experience, but finally as a relatable main character - a girl :) got to focus on my favourite character Sylvie again and play some minigames along the way, including a whole game of Go, very much recommended!
I just dipped into My Silly Science Summer and it’s super cozy and cute. The time-travel setup is lighthearted, and those tiny puzzle bits break up the chatting nicely. Wholesome, nerdy, for a tea and chill session.
This game caught me off guard in a good way. It starts off simple, but before you know it, you’re wrapped up in a really charming story about curiosity, friendship, and a group of girls who each bring something totally different to the table. The pacing is relaxed, the humor lands well, and there’s a nice balance between silly moments and genuinely sweet ones. I liked how it never tries too hard to be dramatic or deep. It just lets you enjoy spending time with the characters and watching them grow closer. The art is lovely, the music fits nicely, give it a try.
