Ran into some similar bugs that others have already mentioned here: the main guy didn't swing his axe even when I hit LMB, and one of my minions got stuck attacking a building even after it was already destroyed. It feels strange that I should have to click on a crate twice to send two minions to it. If one minion can't do anything by himself, clicking on a crate should automatically send two of them (maybe that's intentional, but that's just how it feels to me).
I fell off the edge of the map and wasn't able to get out. Had to Alt+F4. I know you said swimming isn't implemented yet, but maybe add some invisible walls or something to prevent users from falling.
Feels like a very basic prototype for something much bigger. It'll be interesting to see how this turns out. Good luck!
