Improvements in summary include, but are not limited to:

Zoom Mode

You are now able to zoom and unzoom Realms and the Resource Card for a better look as you play. Just click the Realm or Resource Card anywhere but a Field or Resource to enlarge it for a clearer look, then unzoom it when you are done.

AI Bugfix

There was a serious bug in the AI that caused it to behave really erratically in a lot of cases. This has been remedied. I'll likely release an improved AI patch in future, but this should really improve things for a lot of people as it is.

Various polishing and fixing

I polished, tweaked and fixed a lot of little bugs and niceties. The overall experience should be significantly improved for a lot of people.

Polished Tutorials

I did a pass improving the quality of the tutorials, which will mostly be of interest to new players.
