Deploying to Heroku and other platforms

Hi, I had two questions regarding this repo. I am trying to deploy the code to Heroku and other deployment platforms and I keep getting this error below:

**LiveReload running on 35729
info Server running at http://172.19.106.102:9966/ (connect)
4617ms 3.3MB (browserify)
Error R10 (Boot timeout) -> Web process failed to bind to $PORT within 60 seconds of launch
Stopping process with SIGKILL
Process exited with status 137
State changed from starting to crashed**

The port error is happening on each platform. Browserfy seems to have an issue when deploying to a server. It works perfectly locally but would like to see how I can have it running in a development server like heroku.

The other question I had was around starting and stopping the simulator after it started and then restart based on a click function.

Is it possible to change destination after the application is started?

No files, tests, or entry points are named. Start by tracing the deployment startup command and how the server selects its port, then review the simulator's start, stop, restart, and destination behavior; done requires resolving the deployment questions and defining the requested runtime controls.
