The art is great, it feels well thought and controlled. On the gameplay side, it didn't felt that much intentional, like slapping an FPS controller where you can prone / crouch, sprint anywhere, run on water. Music was a tad repetitive as well.
I first got lost running to the water to "refresh" myself to stay awake, missed the slightly signposted pier by going in the wrong direction.
On explorative games like this one, you usually have a really pertinent signposting / landmarking art to direct players in the "right" direction. Probably totally missed the point but I don't think it fits the theme that well. Too vague for me.
Again nice art direction, there's something to be done with everything you have there. I think it needs more intention, more world building.
