Yes and no. I’ve yet to find any code that you put in to gain extra lives or whatever but I have found one tiny little thing you can do to make a huge difference later on in the game.
First search your computer for a file called explosion5.png. This file is the smoke that appears on your screen when the skeleton pirates drop a bomb.
Now open up that explosion5.png and remove the dark cloud graphic so that it’s basically just a blank background. So it goes from this to this …
to this …
Now when you restart the game and a level comes up that your deck is on fire, your view is no longer blocked by smoke and you no longer have to use the stupid water bucket.
Since you no longer need the water bucket you don’t even need to load it up at the beginning.
The Twin Mini Cannon behaves just like the mini cannon, but shoots in two directions: forward and backwards. The damage on the forward shells are small while the damage on the backwards shells is big.
The twin mini cannon (forward shells) do hit harder than the mini cannon does and the cost is exactly the same so I always just use the twin mini cannon, since it’s stronger than the mini cannon.
