Picogame: a game engine for CircuitPython
Picogame is a 2D game engine for CircuitPython by Vladimír Smitka. A native C core handles rendering, scenes and collisions, while the game logic stays in Python – no compiling, no firmware flashing. It runs on the PicoPad, Raspberry Pi Pico, ESP32 boards and the Adafruit Fruit Jam, and can be tried right in the browser.
