I got to level 26 and I found the solution, but the timer is way too fast for me to even complete the level. The 2nd problem I have is when I go to the level selection I have to start from level 24 because the last two levels I unlocked are blocked from being open even though I completed them. I can show a screenshot if necessary where the level bubbles are shown with white where the level looks unlocked, but I cannot click it....

And one of the tags is "relaxing". Relaxing? When under time pressure? I don't think so.

level 30 can be finished without having to connect the left most white piece to the rest of the puzzle. https://imgur.com/a/yVnLMLZ Also a bit more time on level 30 would be nice, I wouldn't have enough time to finish the level if that piece was required. [an option to give 2x more time as an easy mode, or an unlimited time mode would be nice to add to game]...
