For example: - Upgrade for Raids keeps eating my gems and not giving me the upgrade - Settlement upgrades in the map often have incorrect listed requirements (e.g. “Level up 4 more settlements for next tier” when it is actually 6 more settlements) I’ve submitted the bugs to the developer, but they still haven’t fixed them even though several weeks have passed. Also, based on the update schedule of the game, I don’t think it’s getting any new content despite what it says in game and what they are telling people in other reviews. **Developer response:** Thank you for your feedback and for sharing your experience! We’re sorry for any inconvenience caused. Please contact us at support@sozap.mail.helpshift.com with information about your issue and ideally a screenshot of the error you are getting. We'll definitely look into it. ### 1/5 — Copy and paste of the lumber game *2025-09-24* Copy and paste of the lumber game. You have the planter - the machines that dispense the material. The lumberjacks - the workers shaping the material. The truck transporting the logs - the train that transports the material. The forklifts - the drones. The refiners - the refiners. The builders - the mixers. The loading bay - the loading bay. The customers that take the lumber - the customers that take the material. Exact same game. Different skin **Developer response:** Hi there, Thank you for your feedback. We’re sorry you feel Idle Energy Empire comes off as too similar to “the lumber game.” We strive to bring unique mechanics and experiences—mixing idle energy management, resource building, and combat against zombie threats—to set us apart. That said, we’re always listening. If there are specific features in other games you feel we closely resemble (or ones you liked), we’d love to hear them. Your thoughts help us improve in future updates. Thanks for giving us a try, and we hope we can win you over with upcoming content! — The Idle Energy Empire Team ### 3/5 — Good game just some bugs *2025-08-23, version 0.4.4* Game is pretty good not to much to complain about just needs a no ads in game purchase, different way to earn gems its incredibly hard to get them, on top of that metal detectors are also hard to get without pulling out the wallet especially at factory 5 when I did all my challenges for them. Speaking on factory 5 its where I'm at and my mining train is level 31 (Max) and I still cant purchase one more mining train it says "Available in factory 5".Also when you try to upgrade your tap strength the time doesn't continue when you are off game so for example if it's 24hrs you gotta be on for 24hrs. All around decent game just needs some tweaks and fix the bugs. For reference I'm 89.12% map explored on factory 5 with mostly everything max so I play pretty often still would recommend game just needs time. ### 1/5 — Waste of time do not download at any cost *2025-07-29* Sheer greed from the constant adverts you cannot get into a flow and then the app stopped working so deleted and downloaded and it’s straight back to the beginning. Lazy greedy developers doing a fast cash grab avoid this rubbish like the plague and ignore the fake reviews obviously written by the developers friends and family. **Developer response:** Thank you for your feedback and for sharing your experience! We’re sorry for any inconvenience caused. The game is still in its early development phase, we will forward this to our production team. Thank you for playing. ### 4/5 — Great game but with a question *2025-07-24* Absolutely love the game and has been my go to game for the last month. But I’m wondering if the toggle on the storage manager for recurring order should be working? Would be great for me to find out ### 3/5 — Fun, but broken *2025-07-10* It’s a super fun game but there is a bug where you can’t change factories **Developer response:** Hi, Thank you for reporting this, and sorry for the inconvenience. In the current version, the game is designed so that you can only play the currently active factory. Completed factories begin generating idle exploration tokens once they’re finished. Thanks for playing. ### 1/5 — Buggy *2025-07-10* There’s too many bugs in the game. For example: - Upgrade for Raids keeps eating my gems and not giving me the upgrade - Settlement upgrades in the map often have incorrect listed requirements (e.g. “Level up 4 more settlements for next tier” when it is actually 6 more settlements) **Developer response:** Thank you for your feedback and for sharing your experience!

We'll definitely look into it. ### 2/5 — Game won’t open or load anymore *2025-06-24* I keep trying to load the game and it’s just stopped loading and won’t work anymore **Developer response:** Thank you for your feedback and for sharing your experience! We’re sorry for any inconvenience caused. The game is still in its early development phase, you will need to reinstall the game and try to run it again. ### 4/5 — Not working after the update *2025-06-24* Game is good. But has stopped working after update ### 2/5 — Crashes after update? *2025-06-23* Won’t open past slash screen, crashes, was hours of fun building, but now nothing. **Developer response:** Thank you for your feedback and for sharing your experience! We’re sorry for any inconvenience caused. The game is still in its early development phase, you will need to reinstall the game and try to run it again. ## Frequently asked questions about Idle Energy Empire ### What is Idle Energy Empire about?
