@Louisa; Well done building on your previous example. From a design view, try to keep the follow up screen in the same graphic style. use the same fonts and try to use some of the color found in the background from the main screen to keep that unity you've got going on.
@Josh; Love the picture scroll on the fly-out. Well done
@Daniel; Nice work on those hover actions. I've been meaning to try them out myself. Like I've mentioned before you do good stuff with just PowerPoint. If I where to give some feedback I'd say work on your design a bit more. You've got a lot of stuff going on and I think you can really improve your work if you try to simplify. Make sure everything works together colorwise and use consistent fonts. Your main content pages for example. The Blurred background is nice but makes it hard for a user to view and read the map of the house. On the same pages you've got about three fonts. One title with the map, a title in the room screen and the content of the room screen. I'd try to keep those in line more. A good and safe practice is using One title font and one content font consistently.
@Jennifer; great space tour, love the sound effects. I should really be using more of those myself. The meteor shower was a great idea! Although after being 'hit' half of the planets where grey? I could still click them though.
@Donielle; Welcome to the challenges! I totally agree with David. Great illustration and excellent color combination with the player. I had some trouble finding the (i) icons as they didn't stand out to much but other than that. Nice!
@ Michael H; Very cool 360. Cool that you're actually giving a penalty for clicking around when there is no safety hazard. I kept clicking the arrows and leaving the activity prematurely, even after I'd messed that up several times.
