guimaraf The campaign is live now so I probably won't be making any changes to this game, I will use it as a starting point for any future similar games though.
@Ragevortex Thanks! R0J0hound should probably take a lot of the credit though!
I try to track as much as it makes sense to, e.g. score at the end of the game, how many replays and any external links. I also fire a time stamp every few seconds during game play so I record something for people who leave the game before finishing. Unfortunately a lot of ad-blockers also block Google Analytics which is understandable from a privacy point of view, but annoying when you're trying to get user feed back to build better games!
