Turns out there was a clue for one of them that really helped, but it took me a while to find it. The nuclear waste puzzle almost drove me to quit but I kept trying and then, at some point, got the option to change the difficulty level to easy (not sure what triggered that). Even then it took a few tries but I finally got it. The instructions the game gave were invaluable. Overall I liked it and look forward to the full game! **Developer response:** Thank you so much for playing and sharing such detailed feedback! We’re really glad you enjoyed the puzzles, even though some were quite challenging. We put a lot of thought into balancing the difficulty and hint system, so it’s great to hear that you managed to solve them in the end. We’re working hard on the full version and hope to deliver an even more refined experience soon! ### 5/5 — Interesting *2025-09-14* Spaß gemacht **Developer response:** Danke, dass du Spaß hattest! Freu dich schon auf die Hauptstory! ### 5/5 — Fun. Look forward to more *2025-06-28* I like the more detailed explanation in the waste puzzle. **Developer response:** Thank you for the kind words! We’ll do our best to make it even better. ## Most critical reviews (10 lowest-rated) ### 1/5 — Can’t close out of phone in first puzzle!!!! *2026-03-28* Like another reviewer said… can’t get past the first puzzle, no way to close out of phone ### 1/5 — Stuck immediately *2026-01-02* Stuck immediately after opening scene with my phone showing messages. No amount of clicking or swiping does anything! Am I missing something? ### 1/5 — Bombs out every minute or two *2025-10-28* Cannot play ### 2/5 — 유료구매는 안해두될듯,, *2026-06-02* 겜하다가 중간에 유료결제 처음해봤는데요, 유료결제하고 나서 너무 짧음ㅜㅜㅜ 오히려 무료버전이 훨씬김 굳이 안해두 될듯,,, ### 2/5 — Loved the beginning, now it’s just frustrating *2025-06-24* Newspaper progress isn’t saved. Giving items to pictures isn’t saved. In the 2nd building, there’s 2 parts to making the waste. The first part is fine. The second part needs fixing so it is possible to complete. The directions say “if a neutron has 3 or more control rods adjacent the control rods form a continuous line with no empty spaces in the same row or column all the control rods between them will explode.” This occasionally happens, but not often enough to complete the puzzle successfully. It needs to be fixed so it always happens. It rarely if ever happens to long row / columns. ### 3/5 — I may be a bit slow … *2026-03-18* I love these types of games (rusty lake and the like) but I am Struggling haha. A few more free hints would be greatly appreciated. Spent my £1.99 very quickly. Fantastic craic all the same ### 3/5 — Another nuclear complaint *2025-11-06* Unable to complete the nuclear waste level. Your team has received multiple complaints about this specific puzzle..Maybe that’s a sign you need to change something? I enjoy a challenge, but this appears to be either luck-based or poorly designed/explained. I hope your team uses this constructive feedback, I’d love to finish the game! ### 3/5 — Great game to a point *2025-06-22* Fun puzzles and adventure in the first building. Got to the second building and started the puzzles but had to quit. The game lost my progress in the first building so I had to redo the file sorting and newspaper. Worked on the second building puzzles again but had to quit. All progress lost again. Needs fixing! **Developer response:** We're very sorry for the inconvenience. The save system was originally designed to save progress by episode, allowing players to return and replay specific episodes. However, we understand this has caused frustration. We'll work on improving this system and apply a better solution as soon as possible. Thank you for your feedback! ### 4/5 — Definitely challenging, but fun *2026-05-22* I really liked this game! Very creative. I would give 4.5 stars if I could. Not 5 only because it’s a little too short and a little too infuriating at times (I would have paid for a skip puzzle option at one point, but I did end up solving all of them so maybe that isn’t fair). I look forward to more from these creators and am off to see if they’ve made other games. Well done! ### 4/5 — Very hard but fun! *2026-05-20* Some of the puzzles were too hard for me, but it was a very fun game otherwise! I also couldn’t get the hints to work, but the developers responded on instagram when I got stuck. Would love to see more games from this team! ## Most praised reviews (10 highest-rated) ### 5/5 — Fantastic *2026-05-29* I never feel the need to review but I loved this!

No bugs, no unsolvable level, clever and original puzzles. Wish it was much longer! ### 5/5 — Superb⭐️⭐️⭐️⭐️⭐️ *2026-03-08* Excellent puzzle game with really original gameplay and puzzles. It took me a while to understand the nuclear fission type puzzle but when I understood the rules it was soo enjoyable. I am gutted the demo is over but look forward to continuing this fabulous game. Really interesting and intriguing story. Thank you 🙏 Edit: the full game is fantastic! I played from the beginning again and have enjoyed every minute of this game. The support on instagram is also superb, I had a very helpful reply extremely quickly. Very talented developers! ### 5/5 — 방탈출 좋아하면 강추 ! *2026-03-08* 다소 어렵긴 했지만 참신해서 좋았고 하나하나 풀었을때 쾌감이 장난 아니에요 ! 방탈출 좋아하시는 분들께 진짜 강추 ! ### 5/5 — 예상대로 띵작! *2026-03-07* 노힌트로 깨진 못 했지만 너무너무 재밌고 도파민 돌기도 하고 단서 보고 뭔가 딱 스쳐지나가면서 스토리를 깨닫는 재미도 있어요 다음 편은 언제 나오나오ㅠㅠㅠㅠ ### 5/5 — 오프라인 방탈출에 글보고 플레이했는데 *2026-03-07* 생각보다 더 재밌고 문제도 깔끔해서 좋았습니다 은근 고퀄에 진행방식도 조잡하지않으면서 특이한 느낌이라 끝까지 재밌게 플레이 했네요 힌트는 두번?쓴듯합니다 딱한가지 아쉬운 점은 결제하고 나서부터의 플레이 타임이 생각보다 길지 않은 느낌이었어요 그래도 앱 자체 퀄리티는 좋아서 결제할만 하다 생각합니다 문제가 딱 깔끔한 느낌이 드는 방탈출 게임 극호... 다음 시리즈로 내시면 또 구매할 의향 있어요 재밌는 게임 감사합니다 ### 5/5 — 재밌게 플레이했으나 아쉬운.. *2026-03-07* 간만에 재밌는 퍼즐게임을 했어요 러스티레이크 느낌이나서 좋았는데 퍼즐 난이도는 조금 있는편이었고 다만 데모 플레이 후 결제했는데 크게 뭐 한거 없이 엔딩이어가지고 조금 부족하지 않았나 싶어요 이게 끝이라고..? 하고 끝났네요ㅜㅜ 아쉽긴하지만 재밌었어요 ### 5/5 — Very Creative Puzzles! *2026-02-25* Wow, never played a game like this before. Extremely creative and challenging (but not annoying) puzzles, compelling story and suspense. Can’t wait for more games!! Also, love how there is a choice for difficulty level. Puzzles are so well designed in that it can be super easy to pass (by lowering grade threshold), but players want to have that challenge. Also played previous game, Raven Field, and Loved it too. Please keep making these games!!! **Developer response:** Thank you so much for the kind words. We’ll do our best to live up to your expectations and bring you an even better game! ### 5/5 — Very Creative Puzzles! *2026-02-17* Wow, never played a game like this before.
