Has potential if given significant improvements.
1. Difficulty is somewhat broken when I need to find light but can't see more than a few feet in front of me (i.e. I'd need to memorize). If I were really in this scenario, I should theoretically be able to see to the end of a hallway or something. I would consider enlarging the line of sight.
2. The deranged opponents are seemingly unarmed yet making contact with them results in instant death? Perhaps include an HP bar.
3. Dealing with deranged passengers and the need to move fast for light at the same time seems unfair from a gameplay perspective; the only obvious way to detect the crew is visually with the very small light source (#1 makes this worse), and scanning around carefully isn't feasible with the restrictive time limit in darkness. I would add/enhance audio cues to the crew members, utilizing surround sound.
