One direction I imagine our game going towards is a dark, mysterious, tense feel. The ocean can be a dangerous place, and there is much about it we don’t understand.
The ocean also has a calm side. Exploration can be light-hearted and fun, with bright, sunny colors that bring about relaxation.
A third direction our project could go is more of a directed, quest approach. This could be searching for treasure, deciphering clues that a missing crewmate left, etc.
