Pewmulator is an emulator for the PewPew library that lets you play the games writen for the PewPew devices on your computer. It comes in the form of a Python 3 library that uses PyGame under the hood to implement all necessary parts of the PewPew library.

Note that the code is then being executed with Python 3 and not CircuitPython, so there may be some differences. The most obvious difference is the amount of RAM memory available — so if you write a game in Pewmulator, chances are it won’t run on PewPew because of lack of memory.
