Hello Nathan,
first of all, I would like to congratulate you. Another great release!
Better yet, we can finally buy it and support your amazing effort!
Here, I will make a few suggestions:
I have noticed several spelling errors in the documentation and one weird explanation as well I wanted to clarify. Would you like me to report those as well or the documentation is not finished?
Also, a small oops, on the download page:
Accessible Chess v1.0 setup.exe(0MB), Version downloads: 14. total downloads: 14. I know your programs are small, but 0 MB?
Now, on to the program itself.
First, when you start an offline game, it would be great if you could choose some options. Mainly, the difficulty of the AI, which is a common setting in Chess programs, but even more importantly, whether you want to start out as white or black. Beginners especially would prefer playing as white while starting out, but in general it is a thing worth customising.
Second, I would really rework one part of the board navigation. If I keep going right, for example, I am told once I reach the end that I am at the far right of the board. This is in my opinion completely useless, especially since the square is not repeated. If you really want this information, perhaps a short sound once you reach one of the edges, and instead of screen reader speech telling you this, just say the square name which would for me personally be more useful.
Also, quick navigation between pieces would be nice. Since first letters have already been taken up, perhaps holding ctrl and pressing keys like K, R, Q, N,P, N and B would allow you to jump to a piece on the board. Obviously, B here represents bishop, K king, N knight, Q queen and so on.
Most important of all though, I am not sure if this always happens, but it is very frequent for me.
If my opponent, for example, captures my bishop with a rook on E4, and then I have another piece that can move to E4, after focusing on E4, no piece is announced. My opponent's rook should be spoken. Similarly, even if I play there, no capture is announced even though everything seems to play out correctly. This could be a bit misleading. Let me know if this doesn't sound clear and I can make a short recording.
Also, but this is only a personal opinion, I would really make the sound when a piece is captured much shorter. This musical jingle is nice, but before it is done playing, another turn already happened, and possibly even another capture but there is no sound to signify that.
All in all, with some more bugfixes, this should be a great release! These bugfixes though need to happen before anyone plays online, especially the bug where after capturing a new piece is no longer announced as you navigate to that square. Speaking of online, is it running on your own server? Do I need to forward ports to play?
For now, these are all my remarks. Thanks once again and good luck.
