     const map = LEVELS[CURRENT_LEVEL].map.split('\n')
     const level = addLevel(map, config)
     const utility = add([
       multiplayerCamera(),
     ])
     setGravity(config.gravity)
     setBackground(config.backgroundColor)
   
     on('hurt', 'alive', (obj) => colorShiftFx(obj, { color: 'ff9b9b' }))
     on('hurt', 'alive', () => play('hit'))
     on('hurt', 'player', (obj) => obj.play('worry', { speed: 2, onEnd: () => obj.play('idle') }))
     on('jump', 'player', () => play('wooosh'))
     on('drop', 'player', () => play('off'))
