i really like the concept but this game needs much improvment on the interface, its insanly difficult at times, things to improve would be, make units able to drag a box and select multiple or all units, much todifficult to perform some actions when having to move each individually *such as during a zombiwe attack and trying to ahve an unarmed builder flee while an armed character engages. also make the AI able to recognize and be able to move around walls and access doors, way to hard to try to get a harvester inside ur structure to return to chest and yet keep an eye on other units in the field, these 2 things alone would make the game immensly more enjoyable, other than this is solid game, my rate would be 4 stars but because these features i mentioned above are not implemented and are SO curcial i have to be pretty strict on the amount of credit you get, nearly every rts made involving a unit useage structure such as this uses the "drag box select" and allows units to recognize obstacles and move around them. i would love to see a 2nd game of this made with these features and a few fine tweaks, and one last thing i noticed was that a gun cabinet costs 24 ammo to make, but i had already had to deal with some zombies before i go that far in building so i was essentially on a path of having no ammo and having no way to make more, this is also a huge flaw
