This is simultaneously the most impressive tech demo I've ever experienced and the most terrifying thing I've ever experienced in a game, at least as an adult. Holy hell that ocean map is terrifying, I jumped in the ocean twice and both times I almost immediately hit the escape key because that bottomless ocean scares the absolute shit out of me lol.
Someone please develop a game with this, I would kill for a game like Bioshock or Soma that uses this tech. Youtube videos don't do this justice, it looks incredible.
I think the main thing I would ask for features wise would be better interaction with the player's model, it feels like the simulation doesn't conform to the player's model as well as one would think, there are ripples and it looks really nice but that's one element that I think could be improved a bit, for example waves aren't really affected much when they hit the player model. There's also a couple bugs like the water flickering when the camera is close to it at times, but to my knowledge you mentioned you're already aware of the bugs I noticed. Seriously I can't gush enough about this, there's always room for improvement but to be fair you've already outdone yourself, game devs that could make use of this would be absolutely stupid to sleep on it.
