⚡ Deki Engine: Unity-style editor for ESP32

Deki Engine is an open-source modular C++ game engine featuring a Unity-style visual editor, currently optimized for ESP32 embedded platforms. The project targets devices such as the LilyGO T-Deck Plus, T-Display S3 AMOLED, and the upcoming Elecrow CrowPanel Advanced 7″ ESP32-P4. It enables developers to build 2D games with a workflow similar to desktop engines while targeting resource-constrained microcontrollers.

The editor runs on Windows and Linux, including a compiler for the 2D graphics engine. All components are released under the Apache 2.0 license on GitHub. For development convenience, the engine also supports desktop execution via SDL3 or headless mode without a renderer, allowing logic testing before hardware deployment.

Users can construct scenes visually using sprites, text, particles, tilemaps, state machines, and tweens. The Build panel allows selecting a specific board for compilation and flashing. The engine claims 60 FPS performance on the ESP32-S3. Hardware packages provide specific support for peripherals like displays, touch, keyboards, trackballs, SD cards, GPS, and LoRa modules on supported boards.
