Hello i am an 11 year old boy who wants to learn to code i have created a code and i have tested it on the micro bit online application window and it works fine. But when i download it on to the microbit nothing happens. The confusing thing is that the micro bit is working because i can put and download other code and games on to it. you can look at my code here.Also i am giving you the code in python because i am not allowed to forward files.

input.onButtonPressed(Button.A, function () {  
ship.move(-1)  
})  
input.onButtonPressed(Button.AB, function () {  
shoot = game.createSprite(ship.get(LedSpriteProperty.X), ship.get(LedSpriteProperty.Y))  
shoot.change(LedSpriteProperty.Brightness, 80)  
for (let index = 0; index \< 4; index++) {  
shoot.change(LedSpriteProperty.Y, -1)  
basic.pause(150)  
if (shoot.isTouching(enemy)) {  
game.addScore(1)  
shoot.delete()  
enemy.delete()  
}  
}  
if (shoot.get(LedSpriteProperty.Y) \<= 0) {  
shoot.delete()  
}  
})  
input.onButtonPressed(Button.B, function () {  
ship.move(1)  
})  
let enemy: game.LedSprite = null  
let shoot: game.LedSprite = null  
let ship: game.LedSprite = null  
ship = game.createSprite(2, 4)  
game.setScore(0)  
basic.forever(function () {  
enemy = game.createSprite(Math.randomRange(1, 3), 0)  
enemy.set(LedSpriteProperty.Brightness, 150)  
basic.pause(100)  
enemy.turn(Direction.Right, 90)  
for (let index = 0; index \< 4; index++) {  
enemy.move(1)  
basic.pause(500)  
if (enemy.isTouching(ship)) {  
game.gameOver()  
}  
if (enemy.isTouchingEdge()) {  
enemy.delete()  
}  
}  
})  
Yours sincerely
