This was pretty cool, the visuals were nice and the concept was very serious. I feel the same as Grecha about staying in the one spot the whole game, although the golden fish did make me stray away to go and get it. That being said, there wasn't really any indicator of how effective certain methods were to keeping the fish god away? I'm still not sure if the golden fish actually did anything to increase my survival time.
Another thing, the kayak felt HEEAAVY, which I know is supposed to emulate the weight of the boat and the water, but I would argue it's a bit tooooo heavy.
Still, enjoyed it quite a bit!
