Ayin

• 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 init = fn() {
  return {
    player: { position: { x: 10, y: 20 }, },
  }
};

let update = fn(state, events) {
  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)
