In a game where reflex and timing is the key you would expect smooth and easy control so you could focus the puzzle on pure mind, you would expect to circle to follow you precisely and quickly. No, instead I have a green circle that moves nearly twice as slow as my own cursor. Wth. This is a reflex game, our circle should be moving at exactly same speed. Also the graphics are very outdated, like as if you just copy pasted a bunch of pictures from google. Graphics dose'nt mean everything in a game, but seriously it's 2013, at least show some effort to it.
I feel like this game is meant for drug addicts who are high on LSD in order to test whether they have lost their mental sanity. And yes I have played many other puzzle games and I know what I'm talking about. This is one of the only puzzle games wherein it's dealing with the system itself is a challenge rather than the actual levels. And to think this is a third in a series, that means you should have had two or more chances to see how outdated, slow, and downright awful the very basis of your game is, yet you never saw it. Unless this is your appeal, your way of making your game stand out from the rest, I don't know.
The only redeeming factor is the catchy music. Such a waste.
