• Tiny, procedural, gamedev
• only user input is controller input
• Live code reload
• int, float, string, char, bool, key
• arrays and maps
• variables and functions
• if, loop, continue, break, return
• function call
• first class functions

let setup = fn() {
  return {
    .player: { .position: { .x: 10, .y: 20 }, },
  };
}

let update = fn(state, events) {
  let new = 100;
  state.player.position.x = new;
  return state;
}

let draw = fn(frame, state) {
  frame.clear(0,0,0);
}

let migrate = fn(state) {
    return { .player: { .pos: state.player.position } };
}

• dynamic software updating could occur every frame
• user might be required to migrate the state (migrate function is hashed and only applied on updates when it is changed)
