    setSpriteImage( enemy[i], image )
    setSpriteAnimation( enemy[i], 0, 4, 20 )
    setSpriteLocation( enemy[i], { ( i % 2 ) * 400 + 400, int( i / 2 ) * 300 + 200 } )
    setSpriteScale( enemy[i], { 4, 4 } )
repeat

loop
    clear()
    printAt( 0, 0, "Press X for normal speed" )
    printAt( 0, 1, "Press A for half speed" )
    printAt( 0, 2, "Press B for double speed" )
    c = controls( 0 )
    if c.x then
        updateSprites()
    endIf
    if c.a then
        updateSprites( enemy, deltaTime() / 2 )
    endIf
