The red circles are the player units. You control them. Click on a player unit to select it. Green and brown tiles represent the movement range, red and brown tiles represent the attack range. Click on a green or brown tile to select it, then click the move button to move the player to the selected tile or click the wait button to do nothing. Once you have selected the action, you cannot choose another action again until your turn is up. Your turn is up when all your units have taken an action. Attacking is automatically done after your turn ends. The green circles are enemy units. They always move closer to the player. Your goal is to eliminate all of them. If they do not move after you have taken all of your turns, reload the page.
