Overall, fun game and I found myself playing several times! (Although it might've partially been because I was trying to figure out how it works. Agree with the other comments that a tutorial is needed.)
Fairly often buggies would teleport to the enemy on the browser version, not sure if this was intentional. It is also unclear what scouts do. Also, if your construction facility is destroyed, is there any way to recover from that? If not, why doesn't the game just end there?
Also agree on focusing on making singleplayer the best it can be before relying on several people playing your game to make it fun.
