Building PokemonGo in Pure HTML, JavaScript and CSS

Is it broken on my iPhone or is it just a tilted map with a circle overlaid?

There's a screenshot on the linked site which leads me to believe that is the indented behavior. Doesn't seem that similar to PG, as the title implies.

Yeah, this should be "Building the map view from Pokemon Go! in HTML, JavaScript, and CSS".

Tiny nitpick, but supporting desktops to demo a location-based game seems odd!

I can take my laptop anywhere I want to catch pokemon now!

It isn't that you support desktops so much as you support everything. The beauty of using HTML5 and JS is that you'd actively need to put code in to block it working on desktops.

This is really awesome, fantastic timely example. I love the ability to rapidly prototype with html, css, javascript and third party api's.

Edit; probably a bit too much self promotion, as commented below.

Judging by recent posts your account seems to exist largely to promote lite-engine. I'm no mod but you seem to be sailing close to the wind.

Self promotion is commonplace, acting like a non-interested third party with effusive praise when you're really affiliated with the project... that's when there's a problem.
