Reading about this I first despaired, thinking I would have to do my levels all over again. After thinking a bit more, however, I think that I can actually adjust difficulty without too much extra work. Since my levels are on the hard side, I will just set difficulty conditions on some of the more vicious enemy attacks.
It was great to get information about how to adjust for difficulty. I had not noticed the check for difficulty in D_03-sample.ld, and I see that it will be a lot easier to balance my levels now that I can let the player chose to make it easier.
