I think that mechanic still needs work: I went through several variations on the mechanic and even the stage manager's tutorial of it, but I think it still doesn't adequately get the point across that interruption is always a hidden option in this game — which is why it's currently in the description. Also I was definitely too generous with mostly around 4 seconds for each timer after I decided not to randomize it between 2 and 5 seconds.
Thanks for the input!
