Zooming to full-screen left me with some part outside of my screen (2560x1600) to the bottom and right sides...
Villagers eventually got stuck with their tasks although there were still things to do for them. It seemed like they forgot what they were wanting to do in the middle of the way (still shown as running, but staying in place I guess one reason might be they picked the same resource to harvest or gather and when the other guy grabbed it they lost their target.
Sadly, sometime in the endgame (only one more quest to finish) it froze and I had to reload the page, losing everything.
Apart from these technical issues, it's lovely. I wish there were also multiple different sprites for the villagers as indicated by the title card. Also, it might be useful if you could select a specific villager and assign them a task (or at least put them to idle and clear their memory; it seemed just putting them all to idle and then going back to the same assignment didn't change a thing and only when I gave them all a new assignment and then switched back did they get back to work...)
