The software and beginner's guide isn’t up to scratch, so the 20 projects just aren’t there yet. While the shipping is happening, we’re working on those projects, and the http://flotil.la/start page will change and improve as we do, so that you’re not scratching your head so much when you go there.
The papercraft physically included are the diorama and mood cloud, but there will be others that you can download and print to go with Flotilla, including the full-size digi-pets.
For now, the best bit is definitely Rockpool, but the rest is coming, then it will feel like the complete Flotilla experience.
