When I started my first file and you had to choose between 3 hero's I chose that Shanahasa, just because he looks owning! Later I figured out why I had so many problems in the game..
I think there should be an Add [Amount] Energy, and that you can fill in what amount, instead of add all energy, what cheatinsanity mentioned... Maybe you want to split the energy :S
Did you guys know there is a secret button in the shop?
I have found 2: 1) - press on Blast Co. (the sign of the shop) and you go to the newgrounds site. 2) move your mouse right of the nuke untill you see you can press. That's an alternative button to retry. if you find more pm me or post here :D
