I'm at sulfer for grinder, and tin for material, but still don't get any thing from Rebirthing. I don't know what to do if this gets solved, I will write another review saying it's better💜💜💜💜💜💜 ### 1/5 — Prestige not working *2024-10-13, version 1.10* I love this game so much but the prestige isn’t working for me I’m not getting anything I still love the game ### 1/5 — Does not start *2024-05-28, version 1.10* Game opens but stays at the opening gear spinning. Left it for 30 minutes and no change. ### 1/5 — Game consistently crashes! *2023-12-24, version 1.09* Can’t get past the sodium stage on the grinder. Anytime I move on to the next it crashes my game and closes it completely and forces a reopen of the app which does not save my progress. Has happened about 10 times in a row. ### 1/5 — Crashing *2023-09-23, version 1.09* It is crashing right on start up. Doesn’t get past the loading gear screen. ### 1/5 — frozen game *2023-09-15, version 1.09* Game was good until I tried opening it and it showed me my offline rewards but is frozen on that screen and no way to get out of it. game is now unplayable. 0 stars ### 1/5 — Broken *2023-09-05, version 1.09* Crashes on initial startup ### 1/5 — Crashes on start for me *2023-04-14, version 1.09* I cleared 4 gb of space to guarantee it wasn’t a lack of memory that was causing the issue. A spinning gear comes up with the word “loading” then immediately, it crashes ### 1/5 — Lagggggggg then crash *2021-12-25, version 1.06* I want to give a better rating on your game but until you can fix the lagging and then the crashing it stays at one don’t be get me wrong it’s a good game it just legs then it crashes and when it crashes all the progress you did gets reset ### 2/5 — Furnace doesn’t work. *2025-04-28, version 1.10* Not sure about the furnace tab. I have purchased materials up to Barium but it will only collect in the graphite part of the furnace. No bonus from furnace when I prestige either. Makes the game confusing and frustrating because it seems that it does nothing. Tutorial is no help. ## Most praised reviews (5 highest-rated) ### 5/5 — Enjoyable simple game *2024-12-04, version 1.10* I’ve been playing this for like 8 months now as a slow burner game, I enjoyed it! I would love to maybe see an update or added new features but I know it’s not as simple as that but brilliant free game WITH ZERO ADS!! Absolute rarity now days ⭐️⭐️⭐️⭐️⭐️ ### 5/5 — Worth Playing! *2024-10-02, version 1.10* Loving it, the Prestige option alone makes this game worth playing. But having to grind and earn the chances and Gems makes it better! Thank you for also not forcing ads just to play, very appreciated. And I’m happy to watch for the dmg boost and free 500 gems every half hour. I like to play this while I meal prep ^_^ ### 5/5 — Advertising done right *2022-02-08, version 1.06* This is a fun little game that’s worth your time. This is among the newer games that advertises in the right way. You have to watch one ad to get your daily reward but after that, none are required unless you want a boost or free gems every hour. Watching them are helpful but not required to advance in a meaningful way. I’m currently keeping this developer on my watch list for new games out of principle. ### 5/5 — Straight forward idler *2022-01-23, version 1.06* Grind harder and harder materials. That’s the game. Is fun. Solid developer, give it a chance. ### 4/5 — UI tips *2025-03-02, version 1.10* Love the game so far but it’d be so much better if the screen had more real-estate (space). Make the buttons and bars smaller and hide some of these buttons by adding them under a menu (drop-down) button. Basically making the whole UI more compact/smaller will be just perfect! Also, a bonus tip; if you can, add more sound effects such as rock crushing and friction sounds if you have the time. :) --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
