did you notice that shovelz is able to walk under the RR ... ... I replayed this CL this time my way... first I dug the west holez... got the gauntletz to reveal the ?SS... then after I got the keg of zap cola I dug the east holez and those that are near the RR...
After this CL was released, I discovered the 'bug' which makes Gruntz invulnerable to many hazards placed a X=0 or Y=0 locations ... such as that Rolling Rock. I had intended that to be a minor timing problem to be solved. I imagine that it is akin to the 'bug' which flawed a "Honey, I Shrunk The Gruntz" CL, where the King's Fortress was placed right at the top of the map. Warpstone could enter the Fortress, but the puzzle would not end. Moving the King's Fortress down one square fixed that problem.
I remembered the 'bug' reported about the Rolling Rock, and checked it out tonight as research for part of a new Gruntz Level Editor Manual entry called "Gruntz 'Bugz'". Strangely, the 'bug' did not exist in the version I had on my hard drive ... perhapz I had fixed it long ago, and forgot all about it.
But playing the CL kicked me back to 600X480 screen resolution (which I did not appreciate!), so I decided to see what could be done to fix that annoyance. The result is "Frijid Frolicz2" ... so minor a re-working of "Frijid Frolicz" that I do not feel it worth a new thread.
Two Coinz, 1 Secret and one Warp letter added to the puzzle ... and a little experimentation with 'presentation' in the added area which resulted from expanding the map from 28X16 to 32X24.
There is a second download link in the original post of this thread, where you may acquire Version 2 ... if you have run out of thingz to do with Gruntz.
