### 1/5 — Wonderful game, but major issue.

*2025-03-10, version 1.4*

Game is a perfect time-waster that keeps your brain working. 

However, after several hundred levels, the app now always freezes on the title screen. I can no longer play at all. None of the buttons work, and the background music cuts out as soon as you try to press a button. 

I’ve tried restarting my phone, relaunching the app, etc. I can’t get anything to work.

When it was working: 5/5
Now that it’s not: 0/5

Will gladly change if this issue is patched!

### 5/5 — Big fun!

*2023-11-22, version 1.4*

Thanks

### 4/5 — Keeps hands and mind busy

*2023-07-08, version 1.4*

Great fidget game but WAY too many ads…every 2 puzzles.

### 3/5 — Ok

*2023-05-08, version 1.4*

Ok but waaaaaaaaaaaaaaaay to many adds!😕

### 5/5 — Why I love this game

*2023-04-07, version 1.4*

I love this game because it is so fun and entertaining and I always play it and it always makes me smarter and have a bigger brain 🌸❤️

### 2/5 — soo many ads

*2023-02-22, version 1.4*

ads after every second puzzle smh

### 4/5 — Nice job

*2023-02-09, version 1.4*

Beautiful but so many ads

### 5/5 — Check your direction

*2023-02-07, version 1.4*

This is a fun brain challenge. It doesn’t take that much time to complete. But if you don’t get it immediately, you need to start over again—or go back to where you must change direction. I think I am more intuitive for doing it. I wish I could think more logically. But it’s still fun and you can move pretty quickly with it. No statistics are shown with each puzzle. Nor are any points. And I am glad that there is not a timer to limit your trials. So, just enjoy the process. Kind of feels like the satisfaction yiu got as a child for coloring within the lines!

### 4/5 — Very Fun!

*2022-12-23, version 1.4*

Great game to make time fly by. A good amount of ads :(( but so far it hasn’t got on my nerves too much.

### 3/5 — Fun but too many ads

*2022-12-08, version 1.4*

Overall is very fun and relaxing. However, there are ads every 2-4 rounds which gets annoying after awhile. I don’t mind ads but would like them a little less frequently
