Feldspar is an abstract turn-based board game with an AI opponent. It's like Chess in that you take turns moving pieces with different abilities, and it's like Go in that you place blocks on the board to trap your opponent. If your opponent can't move but you can, you win! Feldspar is written with libGDX and the Google Web Toolkit, so it's cross-compiled from Java into JavaScript/WebGL. You can play it at http://feldspargame.com. It'll also be out for iOS and Android shortly. You need kind of a fast desktop since the opponent AI takes quite a bit of CPU cycles. There is also a blog which describes some of the process of making the game with libGDX: http://blog.puzzlingplans.com Enjoy!
