That was quite fun, being able to setup your own defense perimeter is super cool!
One thing I'm not sure about is what is the intended way to play? I ended up building around the tree with lamps and turrets (which is a nice mechanic) but in that case I'm not a huge fan of soldiers following your cursor. Sometimes I just wanted them to stay still and hold position but they kept trying to reach the cursor.
It would work better if the idea was to explore the map and if you had to be on constant move but then having stationary objects as upgrades and mother trees not running out of energy is discouraging this kind of gameplay.
Otherwise the distrust mechanic is very cool, I would genuinely get mad when soldiers bailed with my gun haha
Cool project, with some extra tweaking it has potential:)
