no progress.
i've been a fan of your endless war games and feudalism games, but this endless war needs work.
as far as the design of the game goes, you used pretty much the same formula. i could easily mistake this for endless war 3, and i expected more considering the improvement from your earlier endless wars.
you permanently made bullets slow instead of fast like they could be in endless war 3. i don't know why you did this, or why you didn't at least leave the option for bullet travel to be instantaneous.
Q doesn't make the allies do a thing, i can't get my good for nothing allies to even act as meat shields.
the grammar is shitty. i apologize if you're not a fluent english speaker, but you could take some time to just revise those simple things and improve the production quality of your games.
the campaign structure is a little strange, i don't understand why you changed it. you have to start any particular set of maps from the beginning, rather than being able to unlock each map and go directly to it as you progress through the game (that formula worked! why did you change it??).
you added a few new guns, but they're unremarkable, and this trait of bouncing shots off of walls is too unwieldy for it to be useful.
in a related note, the map terrain is awful. features that are obstacles are hard to distinguish from features on the rest of the map, and when you have persistent blood and corpses they look sloppily drawn on to the terrain over whatever detail the map might have had.
lying down doesn't do anything except immobilize you, it probably should improve your accuracy and reduce the effect of recoil on your accuracy. i also suggest that sandbags shouldn't provide cover unless you're lying down (as in bullets would zip over your head and you could return fire over sandbags if you stood up).
i wish you would do something different with the way shooting in general works. moving has no effect on accuracy (it should, but it's your game so w.e), and of course the first shot of every gun no matter what goes straight to the center of the crosshairs (this makes a pistol or machine gun as accurate as a sniper rifle...something is wrong with that idea).
my suggestion as far as that whole system goes is that you replace the crosshairs with a circle or some other marking which designates an area rather than a point. and as you already do, the circle or pointer or what have you should expand as you continue shooting, but it shouldn't expand arbitrarily, it should actually give the player an idea as to the range of inaccuracy of the bullet (i say this because with machine guns and the like the crosshair gets bigger when you fire it, but the bullets start going fucking sideways and shit).
alright, i could go on, but the basic fact is, endless war 4 has a few new things and no real improvements in relation to endless war 3. sorry, i'm a fan of your stuff i swear, but i see no progress here in terms of your ability to design and create flash games.
