Ask HN: Faking it, in the hope of making it...

I am not a coder, I design location-specific scavenger hunts and themed games. I was recently asked to design such a game for a mall, and when asked if I could put it on a mobile device for people to download, I said, "Of course!"

Oops.

SCVNGR is shuttered, and I don't know of another platform that will easily support the kind of content I hope to design.

Thoughts? Suggestions? Critiques?

Much appreciated, -s
