Word Connection: Puzzle Game

I like the game. It has been fun. However, it is not so much fun having reached level 40. I can still figure out the words but it seems I am going to have to solve all 10 puzzles or I will lose my progress. I play several games on my device. Before if I was in the middle of a puzzle when a got stuck and needed to play something else progress on that puzzle would be lost. But I have played the first three puzzles on level 40 and hen I went back I had to start over with puzzle one. Not sure how much longer I will continue to play.

My phone has a little screen, so it's hard to read some text (or unreadable, like "solved n of 10"). The next, maybe is a phone issue: At Level 21, it was presented to me twice a game with the "eelssv" characters.

Decent game except for the issue of any progress not being saved once you hit level 40. I'm not sure if it's intentional or a glitch, but I definitely don't like it. The game is supposed to be relaxing, not frustrating.
