sure! this game doesn't have any kind of initiative system, its intended as a sort of free for all. as GM, I usually will effectively let all the players act once in whatever order they choose, then have the enemy/s attack, unless its a bigger and badder enemy then I'll attack every 2-3 turns. this usually lets players come up with clever combinations, like someone freezing a combatant and another player attempting to shatter them, and the whole system is intended to really encourage players being super creative and weird and coming up with the wildest uses of their skills that they can, so anything I can do as GM to encourage that is good!
if you wanted to introduce a more rigid initiative to ease players into the more freeform style, I would go in order of LIFE, with most LIFE acting first and descending, then using the unfilled portions of an enemy clock as their initiative (so starting at 8 would likely attack early, but as they're beaten up they would act further down in sequence).
