Welcome to Rescue Quest Gold forum

I've reached level 129 and am now stuck. Although some of the previous levels have been challenging, I was able to work ou the correct strategy to reach the end. However, I've not been able to work out a strategy to defeat level 129. I've played it countless times using various different approaches and sometimes I've released the spritelings but not killed the 2 monsters. Other times I've killed both monsters but not reached the spritelings. I just can't seem to get all 3 without running out of moves. Any suggestions from anyone?
