WooHoo!!! I did it! I finally got past the electric tiles and the Zbots! That combination is very difficult for me, so I was having trouble, but I finally did it. Great level ol' gramma!
Hi and thank you all for making so many great levels in addition to the fabulous ones already in the game.
Working out, I get stuck with the single coin behind the electric tile.
Is it just timing? I don't see any way for getting one of those metal boxes to shield me from the cannon...
Gee, I am sorry you are having trouble in that spot.
Yes, it is a matter of timing.
SPOILER
As you will notice, the cannons fire at different times.
You are safe standing at the spot just below the electric square, do not collect those coins that protect you yet, so stay there and watch the rythmn of the cannon and the square. When they are in sync, (cannon fire comes across at the same time the electric is on) you will have enough time after that to rush in, grab the coin, and come back to where you were.
You must pay attention when you go thru the green gates to get the bonus coins as well. Watch one electric square at a time, instead of trying to see an overall pattern.
Then you will know when it is safe to move.
