Disclaimer: I'm friends with the developer.

This is a fun game, true to the original. I like the colour coding too. Looking forward to a version with a better AI player. There are some minor quirks which will surely be solved before 1.0.0.

Changing the size of the board may be an interesting idea to toy with. As would a multi-player version, possibly even with 3 (or 4!) dimensions ;-).

The only problem I've got is that the game seems severely skewed to the advantage of the player that gets to go first...
