Fun game

### 4/5 — Great!  (A little buggy)

*2020-12-14, version 1.0*

This game is so fun!!  I did, however, notice some bugs - a few levels have multiple lines of the same color, which means you can’t get them perfect (it seems like the minimum number of moves is calculated based on the number of colors used).  This happens on 7x7 level 496, 9x9 level 30, and 9x9 level 56.  Based on the leaderboards, it seems like this happens in 7 other levels, but I haven’t gotten to them yet!  Other than this, the game is so much fun!

### 4/5 — No Ads, my adz

*2020-11-24, version 1.0*

I just paid for the No-Ad version and I’m still getting ads!  What can I do?  I’m giving it 4 stars.  I’ll give it 5 when I get no ads.
