I have been a long time supporter of this vn and its one of my favorites and as such i can unequivocally say that the fishing minigame is in its most frustrating and off putting state yet. I mean this in the nicest way possible, please just revert the fishing minigame to how it was. It would work just as well with the upgrade system and in the meantime something else can be worked out if you really aren't satisfied with the fishing minigame. Such as adding a way to upgrade the rod or parts of it to improve aspects of the minigame itself such as increasing the size of the green zone or altering the speed of the icon, increase of much progress is gained from a hitting the zone, you could add bonus zones/perfect hit zones, and i'm sure there's more i can't think of at the moment.
