棋盘尺寸只有 5*5*5？

It would be a great idea to implement that not only This but also adding online leaderboard or ranks, achievements...

Will it be a Linux version for this game? Depending on which engine is used it could be relatively easy to do. If it's Unity shouldn't be hard.

I saw a youtube video on 4D chess and I started wondering about how do you actually force checkmate with few pieces (like king+queen). Since this is not at all an obvious question if nobody tells you how even in regular chess, in 4D it would be a hell to figure out, but maybe it was doable to do in 3D. I did a quick research and didn't found anything serious on the matter but I stumbled into this game. It would be very interesting to see and develop theory on 3D chess....
