Yeah, I did not have time for a tutorial. I'm not sure if you looked at it, but the profile of the game has a short overview over controls. Did you unpause the game by pressing space of left-clicking the date in the top right corner? Did the speed selector using the two buttons work? So far I did not implement setting the speed by pressing on the bar, only using the plus and minus buttons.
It is currently intended that only France, Germany, and Austria-Hungary are playable, as only they had formally organized spy agencies at the start date. I plan to make every country selectable and have them found a new agency when starting, but I was also not able to implement that in time for submission.
Why do you think I should avoid bright colors? I personally like a colorful map, and if I only use darker colors the colors look more similar and therefore the countries may be harder to differentiate for people without a good knowledge of the state if Europe at the time. Brown borders might be a nice idea.
Thank you for trying!
