The way you described it, it sounds a hell of a lot like savage two. Which I think A lot of people on here might want to try.
Also, fuuuuuuck shrikes. The only reason I think they arent that competitively broken is that they do very little damage, and dont disrupt much. Unless you have an asshole of a pilot.

That being said, I think the most important thing right now is this. "more control while falling"
We NEED to be able to steer, at the moment there is none, and this is 100% essential. I didnt see it being confirmed, although ill admit I didnt look too thoroughly.

I might have missed it, but having some sort of auto-update would be nice for later versions. As it stands now I don't know/think the game has one, but an auto-update when a new version is released is very important if you want everyone to be on the same page and testing the same version.

It might already be there, but if it isn't, it's something you want to get into the game quick.

I think it was suggested, but thats pretty much a given.
They probably wont be able to update in the background, but theyll probably have a client that does updating like tribes, LoL or Diablo.

You might want to spell check your site. In the "blueprints" section, you have "reasources" several times instead of "resources." U shud spel beter.

ai kno ryt loel

Why is it 100% essential? What makes it 100% essential?

One thing i will suggest would be VTOL aircraft, take of vertically then fly it like a plane, it would be good for transportation of stuff to the top of mountains. Since its faster than a helicopter and can be landed with ease unlike a jet, so it would probably have to be "paid" content.

Not being able to control a character after jumping makes the game feel clunky beyond belief. It makes it hard to jump onto blocks, through holes, etc.
It turns people off a game extremely quickly.

The Devs said they're currently working on a system to make the character react to the environment like the character in Assasin's creed does

In contrast, I think it makes the game feel that much more real. I personally find it idiotic that control in the air has so thoroughly permeated games today. This way, jumping is another skill to master, and it is that much more satisfying when you start nailing all of your jumps (which doesn't even take that long to do in the first place).
