Main pain point is if I’m playing and have a streak so I get the extra boxes. If I pause and come back to it later, it resets and I lose it all. ### 1/5 — Level 895 Stole All My Boosters *2026-06-21* This game is pretty fun - a little boring at times because it always does the same thing like doing the same color over and over and over until that color is finished. It’s also glitchy. I just tried to play level 895 and no matter what I clicked on, it pulled out blue thread even though there is zero blue thread in the whole puzzle. I used up dozens and dozens of magnets and other boosters trying to just get through the stupid level and even that didn’t work because eventually the magnets stopped pulling enough to fill the tray. So I had to close the game and I will be deleting the app because it is impossible to pass the level. Fix your game and replace all the boosters you stole from everyone!! **Developer response:** Thanks for your feedback! We’re sorry to hear about your experience. This definitely doesn’t sound as intended. The issue has been resolved in the latest update. Please contact us at support@virtualprojects.co with your details, and our team will be happy to investigate the issue and assist you further. ### 4/5 — Level 480 doesn’t work! *2026-06-01* I love this game. But when I reach level 480 I have to delete and start over. Level 480 has the wrong colors. When you click one it comes up blue. Then there’s a layer of boxes in the back that won’t clear when you click them. Please fix. **Developer response:** Hello Macapur! Thank you for reporting this! 🧶❤️ We're happy to let you know that the issue with Level 480 has already been fixed. Please make sure you're playing on the latest version of the game. Thanks for your support and happy stitching! 😊 ### 1/5 — R *2026-05-28* Cannot play each color isn’t not the right color it makes you lose every time you try to play **Developer response:** Hello, R! Thanks for bringing this to our attention! ❤️ We identified the problem causing the colors to appear incorrectly and have already fixed it. Please update to the latest version of the game, and everything should be back to normal. Thanks for your patience, and we hope you continue enjoying the game! 🧶✨ ### 4/5 — Glitch in level 7460 *2026-05-24* Great game lots of fun but there is an impassable glitch at level 7460 where the back panel will not unravel. Only half of the colors are true. **Developer response:** Hello, Prettypawslv! Thank you so much for reporting this! We found the issue with Level 7460 and have fixed the incorrect colors and the back panel problem. Please make sure you're updated to the latest version of the game. Hope you continue having fun playing! 🩵🧶✨ ### 1/5 — Loved it but it’s broken *2026-05-22* It’s a great game and I enjoy it very much but level 671 is bugged or broken. The colors shown are not the actual colors so it’s a stab in the dark as to what is what. I tried closing and reopening, turning off my phone and restarting and then finally deleting it and reinstalling only to see all my progress reset back to 1. I can’t believe this and I had just paid $9.99 for the pass that now I can’t even restore that. I feel like I got ripped off and scammed. **Developer response:** Hello, Sniper Cartman! We're so sorry for the trouble this caused. 🙏🧶 The issue with Level 671 has already been fixed. For your lost progress, please reach out to us at support@virtualprojects.co We'll do our best to help and find a solution for your Elite Pass as well. Thank you for your patience and support! ### 2/5 — Tons of ads!! *2026-03-23* There’s nothing unique about this game. And the ads are very long. Deleted it! **Developer response:** Thank you for your feedback. Ads help support the development of the game and keep it free to play, but we’re always working to find the right balance. ### 4/5 — Fun game *2026-02-24* Why does game lock up after you are playing in the game? It happens a lot. **Developer response:** Thanks for your feedback! We’re sorry to hear you experienced this issue. Please make sure you’re using the latest version of the game. Hope you continue enjoying the game! ### 5/5 — Love it *2026-02-03* I absolutely love this game!! It’s a great escape **Developer response:** Thanks so much! We’re really glad you’re enjoying the game. More updates are on the way. Hope you keep having fun! ### 5/5 — More levels *2025-11-11* Keeps saying coming soon! I have over 20,000 threads lol waiting for next level **Developer response:** Thanks for your feedback! We’re happy to hear you’ve enjoyed the game so far. New artworks are coming very soon, and we appreciate your patience while we finish them. We hope you’ll enjoy what’s next! ## Frequently asked questions about Thread Fever ### What is Thread Fever?
