I don't regularly comment on others' games and when I do, I hate to give a negative grade. However, as there are already quite a number of 3D variants, I can only compare this game to some of them.

1. 3D chess creates extra paths on which pieces may move. The most obvious of these is the so-called 'trigonal' path (like a diagonal path, but not colour-bound); various variants have introduced a UNICORN or a MACE as a line-piece to move on this path. A variant that misses this is really lacking something important, I feel.

2. One weakness with the starting position is that a couple of simple moves by the Rook or the Queen can check the opposing King. As white moves first, this gives quite a head-start to white, which is not fair.

3. The piece density is too low. FIDE chess has 32 pieces for 64 cells (50%); Shogi has 40 pieces for 81 cells (almost the same, although Shogi's pieces are somewhat weaker). Changgi (Korean Chess) has a lower density of 32 pieces for 81 points (40%). Now, there's nothing sacred about these percentages, but they have stood the test of time. Having designed quite a few games and playtested them on Zillions of Games, I've found that Changgi's 40% density is close to the lower limit at which one may play a satisfactory game. With too low a density, the players just chase each other around the board forever. (My own Diamond Chess 306, whose Zillions file you can download from this site, has a 38% density, but in two of the variants each piece is really a three-piece compound that can be unpackaged). The popular 5x5x5 variants have a 16 percent density, which I find too low. Your own 32 pieces per 320 cells is only a 10 percent density. You've got to be joking.

Now, some suggestions for you, Hafsteinn: 1. Either borrow a Unicorn/Mace-like piece from other variants to ride the Trigonal path, or modify one of the existing pieces to utilize it. 2. Give us something most of the existing 3D variants haven't got. Leapers, for example. Most existing variants simply extrapolate the Knight's move (one orthogonal step plus one diagonal step) to the 3D board. How about bringing in some new leapers that cover the orthogonal plus trigonal, and diagonal plus trigonal, steps? 3. Increase your piece density! Either reduce the size of the board, or increase the number of pieces. (I know the solution is problematic - I'm working on the idea myself, and it's tying my brain in knots - but we've got to try).
