Nice! Maybe IJKL would work better for moves in the 3rd and 4th dimension.
I'm used to WASDQEShiftSpace for movement in 4D games (or just WASDQE with space for jump if there's gravity)
That does seem like it would make more sense, if I ever pick this up again I'll have to try that
are you the Igor Galochkin who made Minefield 6D before?
Yes, I made Minefield 6d almost 20 years ago
