The game had a nice retro Game Boy feel to it. It could use with some guidance on the controls and how to play. I got past the main screen with pressing Enter, and could move around with arrows or WASD, but the tried Space and Enter, before moving on to randomly pressing buttons to find what did something. I found Z to be the main action button. If there is a cancel button, I didn't find it. You could just list the controls on the game page.
I ran into some bugs while playing. After getting bait and doing some fishing I got the message about being out of bait, but pressing Z to advance the dialog, then tried to fish again, in a loop. I manged to escape by hitting Z and immediately pressing W to go up and away. At that point I also got a message about having caught something, even though I'd been getting messages about being out of bait. When I wen to get more bait I was told I was already baited. I'm not sure if there was more to the game, or some kind of score shown at some point. With the bugs, I ended it there.
