My wife and I have played Helldivers 2 almost since release – a game I can recommend to anyone for its satirical in-game politics alone, if only as political analysis. It contains a minigame called Stratagem Hero that my wife enjoyed a lot.

I always found it slightly funny that she would boot up the high-end PC with its 650-watt power supply for it – admittedly only during waiting times, after which we played the actual game. That gave me the idea of giving her a small handheld to play it on the move.

The hardware is an ESP32 with an integrated touch display and battery management; for the direction keys I used good Cherry switches. About 90 per cent of the code came from an AI – though the prompt for it was hardly shorter. The structure at the start and a number of bug fixes at the end came from me. Anyone who wants to discuss AI use in projects like this is very welcome ;)
