Building a python game currently. Why am I having a hard time testing it as I go along ?

I am currently following a python tutorial book and in it, it walks me along on how to build the game. The book also provided source code if I were to get stuck.

I am using pyCharm and the libraries I am using for this project are pip and pygame. I have went into the settings to make sure these extensions are activated on pycharm.

Anyway, when I compile my game by running it, the window that pops up does not let me see the bottom of it. I can't scroll down in this window and I know the code is good because I compared it with the source code and I have no bugs.

Here is an image of what I am talking about:

Does anyone know what is going on here ? How can I test the game properly as I go along ? I am supposed to have a ship down there and it is supposed to fire bullets (which it is doing), but I can't see the ship because I can't scroll or shrink the size of the window. Thanks for the help !
