Not even sure this can be considered an incremental There's no number, no growing rate of progress, not accomplishing more Just progressing at the same rate, doing the same things, for the same result
It's incrementing the depth the player has access to with each prestige and thereby the number of nodes to "solve", so incremental is accurate. Numbers and an incrementing rate of progress aren't the only things that can be incremented, just very common; they're not a requirement.
