Hm...
I'm surprised you didn't use more commonly seen examples of health bars, such as Kirby games, the Kingdom Hearts series, and Pokemon, oh god, Pokemon...
I agree that people like that are in need of health bars. However, like your other reviewers, I must agree that the commercial lacked something. I paused during your warning screen, and I noticed that our health bar in question protects against water. Many games with water drain your health bars if you stay submerged too long. Other than that, everything was nice.
I'll give you a 9/10, and since you amused me on a slow night, I'll be kind enough to round up to a 5/5.
Good luck in your future endeavors,
