Yeah!! I got the PERFECT in 71:41. BalltlezM, you were right, the RW was in the GP's so I had to start the level all over. Thanks for your help. ILoveGruntz, this was a challenging level with some innovative puzzlez. It took me a lot of time and effort, but the PERFECT is very statisfying!!
I seem to be stuck with two Gruntz in the area with lotz of Brickz surrounding lotz of Rockz. Those Purple SuicideBomber Gruntz will not combine in order to blow a path ... they only run straight ahead (marginally useful) or on the diagonal if I step on an Arrow one Tile away from them (totally useless!) ... they will not step out before lighting their Bombz and starting their kamikaze run. Perhapz I am simply trying to do thingz with those two Gruntz too soon. A comment earlier indicated that the Black Pyramid getz lowered to allow access to the SuicideBomber Grunt on the other side ... something about a Grunt leaving the Purple Multi-Grunt Switch (but I didnt' see any obvious way for him to get back to the PMGS, so didn't attempt such a solution).
