Adds the fishing rod as a permanent weapon in your arsenal in slot 6. This is the same slot as the spawner arm and the 7-S weapons.
Adds a fishing terminal in the elevator room of (almost) every level.
Adds a bunch of new fish to discover!
And perhaps some secret fishing spots...
And more?...
Manual installation
First, ensure BepInEx is installed.
Then, drag the "UltraFishing" folder to the BepInEx/plugins folder in your game files.
Known issues
The fishing rod and fish terminal may occasionally disappear when entering a level. With the exception of the first 4 secret levels, this is unintentional. Restarting the level should fix the issue.
Shockwaves can sometimes make some fishing spots unavailable. Waiting for a bit after the shockwave disappears should fix this.
