Author of the game here. We built Polymon for the Polymer Summit to help attendees connect with the team and show off features of the web platform. Team members all have QR codes on their badges that can be scanned by attendees to "catch" the Polymon. Locations of the scanned Polymer team members are updated on a map as they are scanned. There is also a battle system where you form a team of your caught Polymon and link up with someone near by for a local challenge.
For now, no. But eventually we are considering expanding the game for a few other conferences and incorporate other neat platform features like physical web beacons. Eventually we might add a general mechanic that allows anyone to participate, but in the near term it is just meant to be a reference game for others who are interested in building apps on the web platform.
Yup, the game will be made entirely open source, with CC licensed art and music included. Some of the backend is currently under NDA, so we cannot make the source code public yet, but it's already on Github. We're currently thinking this will happen some time in November.
so is that possible to "open" the game (cos right now those pokemon only available in london and SF) so everyone can play that everywhere? (i plan to let attendees to play this game at future gdg events)
I'm happy to answer any questions.
