Before level 5, we can finish it easily, but in level 10, I don't think it can be passed! It's too difficult. The frequency of earthquakes and fires is very high. We have no way to clear it! ### 3/5 — Free mode for free *2026-01-07, version 2* I love the game and it’s really hard so sometimes I want to play a sandbox mode just for a break but I can’t do that without finishing the whole game and it’s really annoying. Can you please make a free one for anytime or and earlier level Even if I have to pay for it please ### 2/5 — FIX THIS *2025-12-09, version 2* I’m on the second level and I cannot cool the core ITS STUCK PLEASE FIX THIS ### 4/5 — GG *2025-11-24, version 2* Change the M menu please 🙏 ### 3/5 — 2ステージ目のクリア条件は何？ *2025-10-17* 1ステージ目のクリア条件は原子炉を破壊するだけど2ステージ目のクリア条件は何？ ### 5/5 — Great little game! *2025-06-09, version 2* Great little game of balancing parameters. The English could do with a bit of polishing, but it doesn’t spoil the experience. ### 5/5 — Needs updates *2025-03-08, version 2* Maybe you guys could add more updates? Good game nonetheless. ### 5/5 — ok *2024-11-10, version 2* The game is good no matter how un realistic is it but I love controlling nuclear power planet and it very basic ### 5/5 — Fun game *2024-08-17, version 2* It’s a fun game that is almost like a puzzle, worth the dollar. ### 5/5 — Amazing Game *2024-07-17, version 2* I am really grateful that there was a game like this because this is the only one that I was able to find. I had absolutely no problems with it, and I thought it was pretty good. The only thing that I could ask for is possibly more levels and things to buy/unlock. ### 2/5 — This is honestly very unrealistic *2024-06-27, version 2* It’s unrealistic because random earthquakes which happen more then one time also that I kept the pressure steady at 50-54 and the reactor just started to go crazy and explode for no exact reason and that I kept the temperature at 0 because of a earthquake and a fire started and I even had 0 fuel and the temperature skyrocketed towards the max and it exploded ### 4/5 — Нужен режим песочници *2024-05-21, version 2* Игра интересная и в нее приятно играть , но есть одно но, это то что игра со временем надоедает и было бы прикольно если бы ввели режим песочницы и строительства где можна будет строить свой реактор и т.д. Задумка интересная и хоть я понимаю что в игру было вложено много сил , но все же прошу автора прислушаться к моей мысли. P.s: Спасибо за Игру ## Most critical reviews (10 lowest-rated) ### 1/5 — Куда пропал? *2025-06-01, version 2* Разраб забросил игру. Сыровато. Геймплея на 1 час. Рефанд. ### 1/5 — TOO HARD *2024-11-09, version 2* I want money back it’s too to get past some levels with timer either decrease the difficulty or GIVE MY MONEY BACK ### 1/5 — . *2024-10-13, version 2* on level 10 it’s almost impossible because you start with $ 99 and it’s the same as level 8 but with the reactor upgrade ### 1/5 — Level 7 *2024-10-08, version 2* It’s sad that I paid for this garbage. 39 tries and fire and earthquake every time. I’m sorry for any woman you have been with. Correction this bastard has never has a sexual encounter ### 1/5 — Bad to the core *2024-09-10, version 2* I hate this game it’s way too hard for free play it’s just unnecessary so unlock it unless you want one star reviews and to everyone DO NOT GET THIS GAME!!! ### 1/5 — Unrealistic and kinda dumb *2024-07-24, version 2* The game may as well not be a reactor. The temperature and pressure are completely wrong, and you can up the control rods instantly! To pull rods from a reactor it can take minutes to hours. The game’s mechanics don’t work well and you can make infinite money by keeping the reactor safe. How? You use the coolant to bring the temperature down to the negatives, try it. Anyways don’t buy this game. Wait till someone who puts lots of time in a game to make one. ### 1/5 — It needs water *2024-03-25, version 2* Like I thought reactors are inside water ### 1/5 — Nc2 *2023-08-04, version 2* Gioco orripilante. Già può notare una mano insanguinata e una volta che il reattore esplode ce la foto di Chernobyl. (Orripilante) ### 1/5 — Why do you need to do the enrgery *2023-01-01, version 2* 1.Level 7 is impossible everything coming at you 2. Why would the reactor meater go up while an earthquake BRUH ### 1/5 — Ужас *2021-12-01, version 2* Не игра а ужас 1 уровень прошёл а дальше не проходится ## Most praised reviews (10 highest-rated) ### 5/5 — Awesome game *2026-06-13, version 2* I love these kind of games with the multiple different upgrades ### 5/5 — Incredible game! *2026-03-28, version 2* It’s an amazing game. But on level 10 (which is where I’m at at the time of this writing) can u add a good bit of money to start off because I have to push the reactor and turbine to their limits and it takes a good bit of time to get money and I’m being pressured due to the time limit. I was practically going to win when I ran out of time. :( please do something or idk. Thank you for making such a good game. Good job. What I’m asking is just give like $500 starter money or something. But still 5 stars. :) ☢️☢️☢️☢️☢️☢️☢️☢️☢️☢️☢️☢️ ### 5/5 — Хорошая игра *2026-02-11* Разраб добавь пожалуйста механики ### 5/5 — The game *2025-12-21, version 2* It might have typos but its very fun. Worth the money ! ### 5/5 — I very love this game *2025-11-19* This game is so beautiful game and I recommend this game so so so so so interesting and joyful game ### 5/5 — Cool *2025-11-16, version 2* Record high temperature at 33676C at 2694 P bar lol ### 5/5 — LITTERY TO GOOD *2025-10-10, version 2* PLAY IT WORDS CAN NOT DISCRIBE HOW GIOD THIS IS AGFASFFDFCBXFJGGDX ### 5/5 — J’adore *2025-09-08* Big fan of all of your games . 1 2 and 3 ### 5/5 — Не получается пройти 7 уровень😭😭😭 *2025-08-09, version 2* Понимаете игра очень крутая. Но не получается пройти 7 уровень😭😭😭. Пожалуйста сделайте так чтобы можно было пропустить уровни и сразу свободный мод, или сделайте уровни легче. Пожалуйста поставьте полезно чтобы разработчик увидел🥺🥺🥺. ### 5/5 — Awesome game, well balanced *2025-06-23, version 2* Hello, The game is actually pretty decent and I really enjoyed it, a bit short to be honest I wanted to play longer, more options, more reactors but still enjoyable, don’t know why there was confusion for other players this is pretty straightforward game and it was easy You can get hold of it after a couple of destructions, it was good, thank you developer ✌🏻 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
