Once you have your punishing first run, you are ready for the second.
I've sunk a lot of time into it. There are a lot of "focus" interface bugs, but being unity, that canvas click target thing can be cleared up with a bit of friendly community guidance.
My current highest level is 40 -- but I'm gonna try and break that later today.
