Travel with your newly found raft through the ocean and get to The River, fighting against anyone and everything in your way. They keep coming so do not rest. Fight with increasingly harder vessels and environments, while improving your raft with the flotsam you find. If you thought being alone in the middle of the ocean was difficult, getting near The River is hellish. Don't quit, don't die, and you will hear the Roar of The River soon... Or later. If you can.
This is the main menu... Part of it. The capture was using different camera than the in-game one. It is "just" a static low-poly title (still WIP), with the brownish being the background "drape", and the blue part, is a frozen ocean
No idea what that brown thing is, but holy! it is very mesmerizing
