6 modes: practice, easy, medium, hard, nightmare, and impossible. Arrow keys , arrow buttons, or AD to move the paddle. In practice mode, the blocks regen! Sometimes you might need to press the flag a few times to get the win or lose lines to appear. The game is actually really hard because you can never tell where the ball is going to bounce. Post tries it took you for each level in the comments. Sorry if the ball gets stuck in the wall or paddle-clips sometimes. I'll try to improve it. Post any bugs in the comments.
I used the pong tutorial then remixed it into this breakout game.
