### 4/5 — Good but short

*2021-03-05*

A great and user-friendly app for this kind of puzzle, but doesn’t have many levels. Good for stretching your brain over an afternoon.

### 4/5 — Fun, but short

*2018-08-16*

It’s a fun game, but I beat all the levels in less than an hour and a half. Maybe add more levels?
