Dont wanna be an asshole but I must say I agree. To much scrolling, not very friendly for a new player to get into. Some of the icons for the techs doesn't look that good, the turrets and the radar have a whole other style than the others. Rather than an abstract symbol is a plain picture of a turret. What is the upper submarine techs supposed to be? If they now are final.
Not a big issue but worth a mention. Seams to be fun though.
And whats up with the mixing of horisontal and vertical techtrees.?
Edit: Something I learned myself why playing is often or sometimes i miss/forget some techs just because you need to scroll to find them. I have them in mind that i should pick em but i dont. And its the special trooop techs and naval invasion techs, and I guess it just because ju need to scroll to find em. Getting a a good overview is kind of important i suppose. This seams to start to becoming a problem with the new massive NFs and the new expanded techs.
