This zombie guy is hungry but this time he decides for fresh fish than human brain. Try your luck, get to the deepest place and catch as many fish possible. Money for upgrades isn’t missed.
Touch the display to cast the line and leaning the device you try to reach some deep. The money is only for cutting fish to pieces. So when you get some try to upgrade and buy some help in the special shop. Better line gets you deeper to bigger pieces or try new machete for better cutting. Not everything is good to catch.
