Wow! While I'm not a fan of the horror tilesets and probably won't use the first two, I got to say all three look amazing! It looks great, pretty much flawless from what I've seen.
The animations are really smooth too, great job!
Oh, and one more thing: I'm really impressed with how much the third one feels like Lemmings. I've seen many great tilesets, but most have something that makes it feel like it doesn't go with the original tilesets very well. That's why I like to use the Lemmings Plus tilesets: to me, they fit in better than most others. This one, though: incredible! It really looks like something you'd see in the original Lemmings games, it fits the atmosphere and style so well!
