Richard! Have fun today!
Whether you deactivate the alarm or not - the killer will attack.
And what happens to Scott is similar no matter what you do.
So it is a choice.
During the attack:
I vaguely remember playing over and over; to find the different active spots and to find the correct sequence. It can be done. Aggravating but for a non-combatant like me - it was an accomplishment.
Anyhow - I believe there are no other strenuous action in the other episodes. Nothing that is overtly frustrating.
