I love the hand-drawn art (even making the fishing progress bar from hand-drawn bars) and enjoyed exploring the map. The weird fish-like person next to the shop/fish stall is great. The style reminds me of a "flat game" like the ones made for https://itch.io/jam/flatjam2018 .
I was confused at first by the invisible walls but after I realized you could actually take the paths leading south I was able to find the fishing hole. I managed to catch some rocks and paper and almost caught something that was probably a fish but it got away. The mechanics were kind of confusing and rough, but overall I really liked the sense of place.
