I downloaded the Windows version. This was a good prototype. You had movement and actions. You had a world and something to do. Also the in-game instructions were good.
You wanted feedback, so: The music made me want to grind my teeth. I did not like it. I might have played longer if it wasn't so grating. (Sorry.) The fishing rod mechanic was hard to understand. I caught a fish with it but it was pretty much by accident. Mainly I just waded in to catch fish with the net. I didn't get the point of skipping the fish, as there was no points or anything. Other than the music, there were no sound effects.
It's a good start. Keep it up!
