each round one second long, so on your turn you only have time to either move or act or do nothing. This does mean each turn feels really fast
I disagree. Apart from choice-paralysis (do I do nothing again or finally go now?), this approach can either be slow or fast.
If you slap into each action a bunch of modifiers, temporary modifiers, dice counting (large pools), reaction roll, detraction, comparison, etc that will in the end make that one game-second take ages in play time.
Thanks, but I already have that. It did make things better but I was still getting freezes so far
