Click to shoot, press w to move forward, press s to move backward, aim is always on the mouse. The large green ball is the "boss," attack it. Touching green results in a game over. Getting the boss's health below 0 is considered a win. Yellow orbs give you a shield. Please leave a comment describing any bugs you find.
I made this simple game because i really enjoy games and just wanted to show how simple and easy a game can be to make and to play.
