No matter what I do on cave 5, the ghost goblin somehow gets by all my troops without them attacking him or him attacking them - glitch in the matrix? anyways - after trying 30+ times, i quit. I even did EXACTLY what the walkthrough did at the same time.
draw lines, go get bottle of water, drink water, play with dog, check to see - nope level not finished yet, go run 3 miles, come back, watch level finish up, repeat
