Yeah, I just could not figure that one out at all. Very simply deceptive.
This game is not annoying at all! I love it! It's challenging but very solvable. In the day you posted it I got through all the basic levels and transporter levels. I got through 3 of the grand master levels before I saw that you could download the game to your computer. I did so, closed the window, and discovered that the transporter and grad master levels might not be in the game, and at the very least you have to play through all the basic levels first.
Anyway, I'll get back into it some day
