Annoying, Annoying Energy

I think that this game makes energy really annoying. In order to start all missions that are fun, you are forced to use 10 energy each time. Today is my first day playing, so I started out with full energy. I completed quite a lot of missions before running out of energy. However, after many hours, I checked back on the game and I barely gained 10 energy! After a little bit of research, I found out that it takes a whole 22 hours to fill back to 100 energy! What this means is that unless you buy energy, you can only play every other day, and you can only complete 10 missions each time you play. Even though I know that this game has to make money somehow, I think that at least you should make the energy regenerate faster (much faster) or make it less important or allow us to use less of it. In the end, there is not much that we players can do, so this annoying energy thing is going to force me to post on this blog about every other day.
