The art and music in this game is fantastic. The art especially is super crisp and clear. The fishing mechanics are fun, though I think you can kinda cheese the reeling mechanic by tapping rapidly to detect when the line becomes stable without losing a lot of ground.
Also, I maxed out my fish/reel scores after selling all the fish from the lake 1 time. Not sure if that's intentional... also not sure if that had impact on my fishing abilities... it seemed like similar difficulty before/after the upgrades.
