Analytics are something that's well worth putting the time into. We released a demo for The Necromancer's Tale a few weeks ago and here's a heatmap of around 500 play sessions. We can see where players went and where they spent most time. It turns out players went everywhere possible (and one place that should not have been possible!) and poked at everything.
We have also made quite a few bug fixes and quality-of-life improvements based on player feedback. So thank you all for that!
What I can't easily show as a visual, but which is probably more important than this location-based heatmap for game balancing, is a heatmap of the narrative/story data in the game. By recording the "critical path" through the story we can identify precisely where players tended to drop out.
