The game has a tutorial level to tell players the controls and gives them a chance to get used to the mechanics.
I intended to have multiple levels in which players would have to destroy all enemy tanks to be able to continue but i couldn’t get it to work so i made the enemies respawn infinitely and when you destroy one your score goes up. After getting a score of 10 or more the enemies start shooting heat seeking missiles that move slower and follow the player. i also would have liked the firing mechanic to have a timer but instead the enemies shoot every time the bullet gets destroyed by hitting a wall, hitting the player or hitting the edge of the screen.
