Thanks guys yeah, but actually it is called "FireFlight" and will not feature villains. This version of the game is a biofeedback game (for a client) and the user is already 'challenged' very much by relaxing his/her heart. The fireball waves are the most difficult part of the game and sort of a restriction, because the lavapit stage is infinite (in opposite to the green valley- and dark cave-stages before). I reserve the right to make a non-biofeedback game version of the game and if I do so in the future, I will certainly put villains in it like crows, bats and the like.
