Get some new music. The stuff in the tutorial was so bad I had to close the window as fast as possible. No, the mute button was not close enough. Sorry.
Reminds me of a game idea I had one time. Thanks for bringing it to life! (also helps that there's multiple directions on the shield... mine was more of a button-masher)
Characters in the back row must have a ranged or magic attack. Melee attacks from the back row can only be performed when there are no enemies left on the front row.
Seems to be a problem with production in stage 3. It says to build a geothermal plant, but my coal plant won't produce any energy, so I can't. It says my net energy is +55, so I don't see what the problem is. Other than that it's a pretty alright game. 3/5
