Thanks for the review.
There are 3 types of party members.
Standard guy: No ability, just acts as a hit point.
Engineer: Open red doors.
Cultist "cool guy": Was supposed to be a modifier for the ending screen (cultist in your party: good ending, else: bad ending), but was not implemented. He's just a standard guy with different skin.
The flashlight does not affect monsters. A flashlight that attracts or repels certain monsters was considered, but not implemented.
We didn't have enough time to work on the sound and that's definitely a gap we want to fill next time.
