GETTING STARTED 1 - Make a shooting game

This is the first of a series I'm planning for anyone new to making games on PowerPoint. It's a 'Shoot the Spaceships' shooting game based on one of my first ever games made on PowerPoint featured here: My First Games

This one was made on PowerPoint 2010. The original was made on PPT 2003, so this one uses some of the more advanced features that were not available back then such as the 'Trigger' and 'Animation Painter' commands in the Toolbar.

I'd be interested to hear from anyone who is new to gaming as to how this worked (or didn't) for them. Is it too basic, or too far beyond basic, or OK?

 The next one I have planned if for a basic maze game with added variations such as avoiding moving objects and removing barriers.

Any suggestions for other tutorials in this 'Getting Started' series will also be welcome.
