Was a much more engaging way to do a retro with my team, and allowed us to make sure took action to improve over time.
Still some UX stuff being worked out, but gotten a lot better :)
I've used this for half a dozen retros, and this is definitely something worth trying out with your team. It lead to better discussion, faster learnings, and most importantly allowed us to keep each other accountable for necessary change.
Definitely take it for a spin.
