A few quick answers -

-The minigame is aimed at multiplayer first and foremost - we added it to the single player but consider that an experiment. There will be tweaks.

-The tutorial is currently a very basic version of what our ambitions are on that front. The most important part is that it's there now, but expect *many* tweaks. The purpose is also not to explain everything in the tutorial, but just enough to get you experimenting. There will be tutorial sections throughout the beach and in cyseal still.

-The observatory will obviously show you something

-You have a point on the Source being too vague in there.
