Hi, mates,
I have pleasure to inform you that I solved my problem and completed the level The Barriers.
Yes, I did. How? Very easy.
My way: One must place the block onto the plate putting the block in his right hand. This way the block grow up and really activate the plate.
To check your act enter the map. The completed task will show a square figure in the plate. ( Now I may complete the level with closed eyes). he he
2 hints:
1. When you enter an area where yr magic is not active, make some movements to stay at the entrance of same area with enemy before you, this way you are able to use magic.
2. To avoid useless battles with power monkeys goto left upper corner , kill clansmen and you will find special hand-like key. Then go to center of the map, go south and free the monkey king. No more monkeys appeared.
