The first concept was that one, to reflect the bullets to kill the enemies. But when we tried we saw 2 things, the chaos level was insane it was very difficult to see the bullet that kill the enemy. And was hard to focus at the bullet and the enemy at the same time. That why we changed the idea.
About use heart loss instead of death is a good idea, it is something we can change in the future.
The idea of destroy "x amount of capacitors" was one of the approaches that we thought, and use time instead of high score (faster the player finish the game more score). With more time we thought in use this 2 kinds of level per capacitor or per time.
