Pause button to menu broken, an all attack or command all would be needed for this game.
Also noticing Sniper unit shoots past minions and hits larger aliens. Dont know if that is how you want it, but its not the greatest approach
games kindd of dumb. Stopped playing after you remove the starting platform and put spikes under. you drop and cannot jump so its a free fall. I know the game is meant to be hard, but there is a level of difficulty and just broken/bug.
