### 5/5 — Awesome

*2022-05-31, version 1.1*

Just completed the 120 levels. 101 was the most difficult for me. It was a game I looked forward to playing when I had a few minutes of down time.

### 5/5 — 素晴らしい

*2021-12-18, version 1.1*

とてもやりごたえのあるゲームでした。
面白かったです！

### 5/5 — Maddening Fun!

*2021-02-18, version 1.1*

What a wonderful game--clever design, takes one easily through the basics, then gets progressively more difficult.
I found myself infuriated to get down to a -1 that was totally unable to “Zero" the remaing 1. Sometimes I had to quit & return later in a better frame of mind. It is immensely  satisfying to finally complete a puzzle and move on to the next.  More, please!  PaulB
