Very interesting video
it's great to see how the game will play
a few remarks:
- please make it easier to pause /Change speed of the game (without having to open a settings menu)
- submarine preview window is quite dark (is it time of the day dependent?)
- if we click on the base can we have a contextual menu (not sure if it's in just asking

)
- would be nice if the unknown craft would be "clearer" (we have the unknown in the details window but would love to have a ? or specific color in the preview/unit window as well

)
- at 9:53 you have a screen with I guess is height and speed (?) it looks a bit of an overkill and puzzling to have so many buttons, wouldn't sliders be better
and a few questions:
-what makes the icons bigger/smaller on the map (at least the enemy helicopter looked bigger at the end of the vid)
- multiple waypoints I guess will be in, also patrol missions (by this I mean we won't have to monitor how little fuel a plane has before it crashes I guess it'll go back to base on its own or will we?)
- why 3 triangles coming out of the sub at 02:16?
- do plan on making things like simple right click = attack but hold right click would bring a contextual menu with options like "launch torpedo, decoy or whatever"?
really looking forward to learn more about the game, it looks interesting enough for someone who doesn't know anything about navies to want to follow at least hehe
Keep on the great work
