Hi, Wilson! I think it's great how far your project has come!
I noticed something in navigation you might consider. Sometimes you rely on the Next button to navigate, and sometimes the Next button does not take you where you need to go. For example, I need to click Next to progress through the first few slides. But then when I get to the 3 Steps slide, if I click Next, it actually skips over that whole section. I suggest having Next take me through the content as if I had clicked 1, 2, and 3 on the slide.
The same thing happens in other areas where you have me click on the slide (like on Removing the Drivers and on Reassembly). If I click Next on those slides, I miss out on the important content.
Finally, at the end of each of the three steps, it always takes me back to the menu slide. How was I meant to get to Clean Up the Cabinets and Grill Cloths? I just realized if I click Next from the menu slide, that's where it takes me. I'd suggest making the Next button on the Reassembly slide take me on to Removing the Drivers because there's no reason to go back to the menu after step 3.
One last thing, if you're not going to provide added links and documents in the Resources section up at the top, you can remove that link -- click the Player button on the Home tab, and uncheck Resources.
Hope these suggestions help!
