Thank you for trying out! The sink event is up for interpretetation of what is going on story wise. We liked to think when we designed the game that the protagonist is like afraid of coming in contact with water therefore the psychological horror that the character is being draged down in deep water due to maybe recent events or such. But yeah story was not our focus, so there was no writing or such.
But yes this was a kinda stressed out sequence of the game as we had to get it done for the deadline of our assignment, I would personally love to add more content to the "dark water abyss" so it would be easier for the player to navigate and understand that it's not a loadingscreen/bug, as it's very dark down there. :'D
