a fun idea, but it quickly turns into a clicker, just since the turrets are quite weak, ends up meaning that after killing 10 guys, you get one turret that cant actually handle even 1 guy themselves, and i never got a chance to get the strongest one but the piercing one felt like they didn't actually do anything. and eventually placing blocks was pointless cause you placing it meant you weren't killing the shooting enemies who enemas quickly obliterated it.
to be frank its so hard it overshadows the game mechanics.
still fun before it reaches that point
