There is this challenge, where you have to write a game in Python in one week. I never really had the time for it (I preferred Ludum Dare, where you only have one weekend, so it's easier), but I decided to try and enter this time. Of course CircuitPython is Python too, so I'm going to develop a new game for PewPew. But since others wouldn't be able to play it without making their own PewPew, I will also write an emulator for it.

The topic is "They're behind everything". Wish me luck.
