### 3/5 — Need “HARD”

*2019-03-08, version 1.0.7*

I just wants to play HARD level, and also Ai needs bit of improvements.

### 4/5 — User friendly app.

*2018-07-26*

This is a well put together Go app. I find it to be very user friendly though the Readme section does not work for me. I mainly use it to play against the AI. Roughly what levels do the AI’s play at? 
Also when will Hard be coming out?

### 4/5 — Good, but could be better

*2016-04-29*

If you are a Go player, this is certainly one of the better versions available, and certainly sharpens your game. It's very aggressive, and certainly gets you thinking! However, the Go experience could be vastly improved if the computer played white, rather than black (black starts in Go), as with its ability to calculate all the alternative moves, you are at an immediate and huge disadvantage, especially if you are a beginner (or a bit rusty!): and there's no opportunity for handicap stones if you are a complete novice.

### 5/5 — 在这方面

*2016-01-07, version 1.0.6*
