Neat game. The graphics and audio are very nice, and convey a very relaxing vibe. I especially like the way the sky slowly changes from day to night. When it comes down to actual fishing it's pretty simple but still satisfying to catch the fish.
One thing I will say is that it seems this game had some questionable priorities for a short dev time. The polished menu, over world stuff, and the day/night cycle is cool, but I think it would've been preferable to flesh out the core fishing mechanics more first.
