I rarely criticize, but after the amount of time and energy I just exhausted on this game, in my view it has earned it. You must be a hell of a game player, but in designing this game it's obvious to me that you never took into account the average player's ability. I made it to the third level (I believe that to be correct----the falling hearts). I spent an hour trying to get the meter to rise to the top to achieve the next scene, but finally quit because the meter kept dropping to zero; I never came close. Without an explanation, I don't know what the goal is supposed to be. The hearts are flicking back and forth from pink to blue with purple as the median, but they are changing color so fast that it obvious by watching the meter that one color produces a positive and the other is a negative, and I am not sure which. All I know is that the meter kept going up and down; I never got it above the midpoint, so I finally ended the game and deleted it from my drive before I burned out my left mouse button.
If you are going to make a game that difficult, then in all fairness, you should design levels of expertise into the game so the average player can play it.
Sorry about being blunt, but this game frustrated the hell out of me.
Good luck in your future endeavors.
