I have just watched your video. Thank you so much for doing that. It was my dream that at least one person enjoys it for 5 minutes so I have a beaming smile. I made it really quick so didn't make the directions super clear. If you want to collect ammo approach the console and wait for the container to lift. When you have enough Crystarium take it to the container which is indicated by a big ball in the sky. This is how you progress to the next level. Dogs to collect will appear randomly each time the level loads but they are rare so make sure they bark at you when you see one that's a little different. You can then see bios for the dogs you have saved in the Dogèdex. Once you have collected all the dogs you get your trophy 😀
