Sorry, instructions were in description. 4 units at bottom are yours. You left click to select them and right click somewhere to move them. Right click attacks enemies (though is abit janky when enemy moves). The ball is just to stop them ai pathing from start to finish in one click. End goal is to get one player to the gold plate at the top of the map at which point the game ends. Sorry there's not more, it was a very late build and is killing me i can't change more..... Watch out for:
Another Last Stand
In the future
