No, the code looks for how many fish you have. No additional variables set.
As for opening the console, I guess you could goto the trouble of downloading UnRen. Or just edit a single file in the game directory.
<game_folder>/renpy/common/00console.rpy Goto line #108. Change the config.console value from False to True.
Code:
# If true, the console is enabled despite config.developer being False.
config.console = True
Save the file and open the game. You now have access to the console via shift+O.
*Edit: This is the same in nearly every RenPy game that uses the default boilerplate files. Which is like 99.8% of them.
