Level 895 Stole All My Boosters

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!!

Level 480 doesn’t work!

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.

Glitch in level 7460

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.

Loved it but it’s broken

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.
