Thank you for playing! I can provide some hints, though please remove the image from your comment as it spoils the final level.
#1 Hint 1 (goal)
Is destroying all 7 bombs in one chain reaction the only way to do this? What would destroying the 1 actually require?
#1 Hint 2 (process)
Find a chain reaction that kills all 6 bombs in the main room while keeping the player safe. Focus on getting the immediate bomb the player pushes away from the player.
