Not completely functional, because after the first game all the textures were glitched. I like the game though, and I'm leaving 4 stars because I think with improvements this could be a good extension.

this is the best chess i have played!

NOT A LEGAL EXTENSION! THIS EXTENSION COPIES A 1989 NINTENDO OF AMERICA GAME CALLED THE CHESSMASTER!

The game is excellent! We can improve our brain by playing, it can be also played offline the pieces are good the controllers are working, but the sounds look glitchy and low resolution thats all and thank you for the hard work keep it up!!

A great add-on for playing chess whenever you want. Replying to "it just being a picture of a horse", the problem might either be that it is keyboard-based: the mouse doesn't do anything in this add-on. Or it might be that it sometimes crashes. That's quite a big problem. When that happens, I remove it and add it again, and all should work. The settings for the keys are found at Add-ons manager > Chess (preferences).

It is LITERALLY nothing but a picture of a horse and some crappy music.
