Work in progress on some game graphics: Sci-fi themed Sokoban. I have some other ideas brewing too but aiming to publish a little demo game onto itch.io as a project milestone. #pixelart #gamedev #aseprite

Working on some goggle designs at the moment. This is version 2 which I'm very happy with, mostly because they work and don't look like a prop outta the Flintstones. Critical failing on both count of version 1 πŸ˜‚. #3dprinting #prusa #blender

enclose.horse A puzzle game about enclosing horses.

Recycling some old pixel art to jump-start graphics for a little game I'm working on. Tech stack is #C, #SDL3, and #WASM all playing *very nice* together. #pixelart

Coding some sensor firmware with ESP32 IDF took a few weeks longer than I thought it would, but finally all working (again). Telling myself the learning experience was worth the effort. #esp32 #electronics
