I have several negative things to say about the game, the balance is non-existant, there is no direction and the controls are rage inducing. On the positive, the game is unique, with better controls and balance it has potential. I see it as an attempt to do an ambicious game with not enough time. Keep going at it, there is something good that can be found inside this game but its not being shown here.
Theme, sorry, i dont really see it.
Originality, what i mentionend earlier, there is a nugget of gold hidden inside the game, its truly original and it can become a great game, as Mark would say this has potench and its unique. Dont be discouraged and pursue this concept with a better aproach.
