There are a lot of easy safespots, some attacks seem to be toned down from regular LLS, and I managed to beat Lunatic Extra with 2 misses and 1 bomb. For comparison, I've never gotten close to beating regular LLS Extra. I also feel like a lot of content (spells and stage portions) was cut, and while I can understand NES limitations for some of those, there are others that were seemingly cut for no reason. Many attacks also seem to fly by too fast.
Overall, however, I did enjoy the experience. I hope some of these issues can be fixed, but if they can't, I understand.
