Hi! Yes, I'm the designer and developer. Yes, it was made using Visual Studio + Unity 3D + C# + Blender + Photoshop. I agree about the 3d scene having less clarity than 2d to think chess in general. At the same time I'm very happy with my 3d scene and the ability to think chess in it, I've used few tricks in it to achieve that.
When I came up with this variant, I actually went to search if somebody has thought about it before me and at the time the only similar variant I found out had the un-merge mechanic from a site which lists chessvariants. https://www.chessvariants.com/ For some reason I never thought about that seriously. I just feel like the merging mechanic has to have heavy drawbacks too and one of those drawbacks is that you can't cancel it and those drawbacks are what makes the decision making interesting! And I actually discovered later on that there was chess game called chessplus, which had the same basic idea. https://chessplus.com/ But I didn't like their other rules. For example this sounds too wild and unbalanced to me: Gain extra queens quickly by moving a ‘merged’ piece containing a pawn to the far end of the board, with 3 extra queens included for a knockout finish. And I didn't like the unmerge idea either, chessplus had that.
Yes, I've been afraid of getting offended. But I'm also stubborn and confident with my own views! Also I come from Finland and it's kind of the baseline of our culture that people can tell more what they think than in I guess any other cultures and sometimes that also causes hurt feelings, but Finnish people also know how to be silent vey well.
The game seems to turn the long standing classic game into something different. Your thoughts?
