The Last mission possible

[gamitech]

I am a guy that enjoys the small levels and first when I played the game I stumbled upon the "Mission Possible" levels.
I managed to pass all of them untill the last level.
Do you guys have any demo or tips for me ?
The last level of Mission Possible, seems that I can't figure our the correct order of moves, or I am missing one or two tempos somewhere.
Please give me some advice/demo

I'll give you some advice. At the start of the level, there is one of the three embedded emeralds which is only obtainable without blowing up the exit via a laser beam. Try to create a path for the laser to blast that embedded emerald. Hint: you will need all gems present in the level and a minimum of 7 timebombs.
