🚀 How to Get Started
Setting up your game folder
- Create a new folder on your computer, call it something like
SpaceTurtleChomp - Download all the files above and save them into that folder
- Open IDLE (it comes with Python, search for it on your computer)
- In IDLE go to File → Open and open
turtlegame.pyfrom your folder - Press F5 or go to Run → Run Module to start the game
- Use the Left and Right arrow keys to steer Chomp, and Up to go faster
Important: all nine files must be in the same folder. If the sounds or background are missing, Python won't find them and the game will show an error. When in doubt, download everything and keep it together.
Don't have Python yet? Download it for free at python.org/downloads. Install it with the default settings and IDLE will be included automatically.
