I built the game to play in small resolution, so I find the text is easier to read that way haha. The final 2 heart spells are lasers. It's not described very well but you hold space to shoot them. This makes clearing the bricks a million times easier. I had planned (and had created) a powerup originally that allowed you to direct the ball with the paddle, but was having a hard time balancing it so I scrapped it before the final version, but I think it would improve the flow quite a bit if it were re-introduced.
There are 2 bosses right after that breakout.
Thanks for playing!
