I think this should be a third period only game...

4 minute periods really fudges the clock , screws up PPs and PKs or you make them realistic and people use them to troll and extend game times... 

At least if we play third period hockey ,  the clock gets screwed less. And we still have overtime.  And you can have the gam face up/down still if youre playing a buddy on the couch.

What nhl game do you see almost 2 minutes of game time go by for someone to skate to the bench and line change ... a quarter of the clock can be spent line changing every period.  Which is why I suggested no animations for line changes,  just a blip and change.  There isn't enough time for the animations. Or the goalie takes wayyy too long to get to the bench for an extra skater .

3, 4 minute periods are bad.
