Short and sweet. Subtle changes in the environment and inside the sub really increased the tension at just the right pace, and it was magnified by the tight quarters of the sub even though you have a sea to explore. The scare was perfectly executed at the right time and it's rare to see it done so well. I only wish the end had a tiny bit more to see, it seemed to end a bit abruptly without giving enough time for me to process it and feel anything as the longer paced rest of the game did. The end can still be abrupt but I felt as though the build up could have been more involved. Sound, music, and lighting matched everything very well. Overall, fantastic for a short experience in this environment.
