Interesting that one of the stopping mechanisms is the edge that also (albeit in a very different way) affects Edgehog pieces. Am I right in thinking that noncapturing moves in this game are normal?

What happens when a piece captures, turns, captures again, and has the adjacent cell in its next direction occupied by an ally? Does the move stop with the second capture? Does this also apply to a third or later capture? What if the first capture has one of its potential next directions blocked, by an ally or the edge of the board? Must the piece turn in the opposite direction or can it use the block to stop? What if both sides are blocked?

This game can be seen as a 'Curved' version. It occurs that there could also be a 'Crooked' version in which turns within a move alternate between left and righr. I can see that this latter version reduces the potential for maximum capturing, but it has the advantage that Pawns could be included. A capturing Pawn could make either another capture along the other diagonal (either to an enemy-occupied square or En Passant) and continue alternating between the two. The move would end either with an orthogonal step to an empty square straight ahead or by being blocked - by the absence of a valid capturing or noncapturing move. Promotion would be considered to happen after a move had been ended by reaching the edge of the board and the move thus be unable to continue through promotion.
