I was not expecting the game to be this good at all. The concept is really cool, rage mode stopped me from raging, and actually made me want to lose to make the game easier and more fun. This matched the concept 100%, so thats 5 stars there from me.
Personally, I would like to see some better graphics, the style was good, maybe more detail would be nice. Perhaps a puzzle that requires you to go to rage mode to get to a certain bit, or a door that only opens in calm mode. I think there is a lot you can do with this concept, and I hope you continue with it.
An excellent game, I enjoyed playing this. Very creative! One of my favorites.
