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.)

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.
Eğlenceli bir zaman yolculuğu macerası yaşayın ve bir bilim kampında ilginç kızlarla arkadaş olun. Gizemleri çözüp zamanınıza geri dönmenin yolunu bulabilecek misiniz? Seçimleriniz kendi hikayenizi yaratacak! Zorlu bulmaca oyunları ve benzersiz sonlarla dolu.
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
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!
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!
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.
My Silly Science Summer in the Past is a cheerful visual novel that blends time travel, science-themed comedy, friendship, puzzles, and mystery into a compact adventure. Developed by TBF and published by TLS, the game follows a curious female protagonist who becomes involved in an unusual experiment and unexpectedly ends up in the past. Instead of immediately finding a way home, she becomes caught up in the activities of a science camp filled with eccentric personalities and questionable experiments. The resulting adventure balances the larger problem of returning to the correct time with smaller mysteries surrounding the people she meets. Much of the game's appeal comes from its four prominent companions: Azuki, Marie, Patti, and Sylvia. Each girl contributes a different personality to the group and gives the protagonist another reason to investigate her unfamiliar surroundings. Azuki is an enthusiastic astronomy fan with an affection for science-fiction stories, and her tendency to speak about unusual ideas with surprising confidence makes it difficult to determine where imagination ends and genuine knowledge begins. Marie is considerably quieter, coming from the countryside and possessing impressive mathematical talent. Her reserved nature makes getting to know her feel like a gradual process rather than an immediate friendship. Patti represents the more chaotic side of science. Her fascination with physics is accompanied by experiments that can involve explosions and other unpredictable consequences, allowing her scenes to provide some of the game's most energetic comedy. Sylvia stands apart from the rest of the group. Known more formally as Baroness Sylvia von Tensberg, she is aristocratic, sharp in her manner, and interested in art rather than science. Her presence at the camp therefore seems unusual from the beginning. Discovering her reasons for attending becomes part of the mystery, giving the player another question to pursue alongside the protagonist's time-travel predicament. An important characteristic of My Silly Science Summer in the Past is its emphasis on platonic relationships. The friendships are not simply stepping stones toward conventional visual-novel romance routes. Instead, the story focuses on learning more about the girls, understanding their individual personalities, earning their confidence, and discovering the secrets surrounding them. This gives the cast room to develop as friends and companions. The approach suits the relaxed atmosphere especially well, since the protagonist's summer becomes memorable because of the people she encounters rather than because the game is constantly pushing romantic developments. Although reading conversations forms the foundation of the experience, the game incorporates puzzles and decisions to provide additional interaction. The puzzles are particularly appropriate for a story centered on a science camp because they encourage curiosity and problem solving without attempting to turn the experience into a complicated scientific simulation. Choices also influence how events progress, ultimately contributing to multiple possible endings. As a result, players interested in seeing everything have reasons to revisit decisions and experiment with alternative paths rather than treating the story as a completely fixed sequence. The time-travel premise gives these relatively small-scale events a stronger narrative purpose. The protagonist has an obvious long-term objective in finding a way back to her own period, yet the people and mysteries of the camp continually give her reasons to become involved in the past. That contrast works nicely. Returning home is important, but so is understanding what is happening around her. The unusual experiments, suspicious circumstances, and occasional scientific disasters help keep the adventure moving while allowing comedy and character interaction to remain at the forefront. Visually, the game adopts a colorful and deliberately cute presentation that complements its wholesome personality. The illustrated characters and anime-influenced designs reinforce the feeling of a playful summer adventure rather than a serious examination of temporal physics. Its presentation is most effective when combined with the humorous dialogue and exaggerated scientific situations. Experiments can go badly wrong, personalities clash, and seemingly ordinary camp activities can become strange, yet the atmosphere remains welcoming rather than threatening. This makes the game particularly suitable for players wanting a lighter narrative experience that can be completed without committing to an enormous story. The modest scope is both an advantage and a limitation. Players who enjoy concise visual novels may appreciate an adventure designed around a manageable weekend-length experience. On the other hand, those expecting extensive role-playing mechanics because of the game's genre labels could be disappointed. This is fundamentally a story-driven visual novel supplemented by puzzles, decisions, achievements, and branching conclusions. It does not attempt to provide elaborate combat, deep character statistics, or the systemic freedom of a conventional RPG. Likewise, its intentionally wholesome tone may not satisfy players looking for darker science fiction or intense dramatic conflict. The production also deserves consideration because the Steam description openly discloses the use of AI-assisted content. DeepL was used to assist translation, AI tools assisted with image generation, and some music was generated using AI, with additional information concerning the generated material available within the game. This transparency allows players to decide for themselves how they feel about those production methods. The game also supports Windows, macOS, and Linux, making the experience accessible across the major desktop operating systems. Overall, My Silly Science Summer in the Past works best when approached as an affectionate and slightly ridiculous science-fiction vacation rather than a complex time-travel epic. Its strongest qualities come from the contrasting personalities of Azuki, Marie, Patti, and Sylvia, the unusual focus on friendship, and the way puzzles and branching decisions complement the visual-novel structure. The mystery of returning home provides direction, while the individual stories and secrets of the camp provide the personality needed to make the journey worthwhile. It is lighthearted, approachable, occasionally absurd, and clearly designed around curiosity and companionship. Players seeking a free visual novel with a cozy atmosphere, science-themed humor, puzzles, multiple endings, and friendships at the heart of its story should find plenty to appreciate. Rating: 7/10
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.
