Are you new to using CircuitPython? No worries, there is a full getting-started guide here.

Plug the PyGamer into your computer with a known good USB cable (not a charge-only cable). The PyGamer will appear to your computer as a flash drive named CIRCUITPY. If the drive does not appear, you can install CircuitPython on your PyGamer and then return here.

Download the project files with the Download Project Bundle button below. Unzip the file and copy/paste the code.py and other project files to your CIRCUITPY drive using File Explorer or Finder (depending on your operating system).

Drive Structure

After copying the files, your drive should look like the listing below. It can contain other files as well, but must contain these at a minimum:

High Score Configuration

The game supports different configurations for high score. It can be disabled entirely, or it can be enabled and store data with either NVM, or SDCard storage. To configure it uncomment the appropriate version of the constructor call with configuration argument.

# create instance of OctopusGame
octopus_game = OctopusGame()

# uncomment this instead, to use NVM highscore
#octopus_game = OctopusGame(high_score_type=OctopusGame.HIGH_SCORE_NVM)

# uncomment this instead, to use SDCard highscore
#octopus_game = OctopusGame(high_score_type=OctopusGame.HIGH_SCORE_SDCARD)
