Originally posted by leodIt's not even new, it's been well known for years, it was used in VLDC8 a little bit and then again in VLDC9.
I remember Sokobansolver's level in VLDC7 used it too. Probably goes even further back than that (Morsel mentioned 2006).
I like tile 1F0, despite making jokes about it all the time in the VLDCX forum. It's very much a neat, underused (until recently) gimmick that people who are competent can do some pretty impressive stuff with. Pyro's level this year is the best use I've seen of it thus far, and if other people can follow suit, then that would be pretty awesome.
I don't think there's so much a "hate" for it, but rather, as other people have mentioned, it seems like everyone and their dog is jumping on the 1F0 bandwagon. If you want to impress people with it at this point, you have to take the gimmick a step further and utilize it in unique and exciting ways. Sadly, most people who have just discovered it this year are using it in a bare-bones fashion and not reaching the creative level required to wow people.
