Scratch

Hey, I'm new and have been messing around with scratch for a couple of weeks. I've put together this pretty much by myself through trial and error (mostly). Fun stuff!!
My daughter uses it in one of her classes and I decided to give it a go. Looking forward to comments/advice on the scripts.
This demo/beta features:
Multiple ship 'costumes', weapon powerups, a shield powerup, number of ships (not a counter), a life up, and a ring 'thing'... I'm sure my scripts (blocks?) aren't as smooth as they could be but I'm a noob... Sometimes the powerups don't work so I'm guessing I have to make smaller blocks? Anyways... Link below:
