This Custom Level was originally submitted to me in June, 2010 as "Test". I dropped the ball, and forgot all about it, thinking this was one of my (many) false starts on a CL. Bringing my GruntzExtraz DVD up-to-date (which involved removing any of my own 'in-progress' efforts) I came across this one, viewed it in the Gruntz Level Editor, and realized it was NOT mine!
That's pretty interesting. I randomly discovered this level while searching the indices. This level suffers from the same problem that I mentioned in this thread.
The coins should be hidden behind trees, but they appear above them and because of that they are very easy to notice to any player. I checked, the logic of the trees is EyeCandy, not BehindCandy. So it appears I'm not even the first person that the bug happened to, just the first that noticed it.
