Making a game on a custom bytecode VM in 7 days and 3kB
A developer created a shoot 'em up game in just seven days for the Langjam Gamejam, embedding a tiny custom bytecode VM and rendering graphics with a fullscreen pixel shader. The resulting 3kB Windows executable was part of a game design that combined language tooling, game development, procedural graphics, and demoscene-style size constraints.
The developer, inspired by demoscene productions and the 2004 game kkrieger, aimed to explore the potential of embedded interpreters to create smaller executables while still delivering an engaging gaming experience.
