great question! I would say overall spelling does not matter, I definitely don’t want that to be a barrier for players or have people feeling the need to dig through the dictionary before playing. I’m sure I’ve spelled words wrong on accident while playing and just went with it, nothing bad happened and other players probably don’t even notice!
I think an honest attempt at the start of play is valuable though. Like starting with the word Lazerswoardbarrrronesss and using fractures to then those extra letters into Life or otherwise abuse it to come up with weird words later is against spirit of play (clever as it might be to plan ahead like that!)
