Why only 1.8.9 dude? Your first version was 1.7.10.....I was thinking the next was 1.8 (And trully I wishing was 1.8 first because I'm on that version and don't thinking to upgrade to the new versions....well...I only wanna know, I always make a modpack and without your mod it's uncomplete....welll....I wait, maybe on a future stablish a 1.8x version (I'm not forcing you to, only thinking for myself), good luck).
I know most mod packs revolve around 1.7.10 still, but IMO things should start moving on. I just feel like 1.8.9 would be the next logical step for mods as it should be one of the last, if not the last version of 1.8 before 1.9. Thus I don't really see any point in making this mod for earlier versions of 1.8. Apparently this should also be compatible with 1.8.8 too, but I have not tested this myself. EDIT: I know not many of the larger mods support the latest version, but that should change over time
Regarding 1.7.10, functionality in the latest version is exactly the same as the 0.2.0 backport, with the only changes being aesthetic (the block model), along with a simple version check and notification system. So I don't really see a need to back port this.
So...maybe the last update on 0.2.0 of 1.7.10 of the mod works on 1.8? Well, I doesn't know but I will try it, thanks for taking the time for answer me.
PD: Only for a little opinion, it was funny on the future it the mod works too on the little ender silverfish, you imagine it? That little purple things dancing to try to escape from the block radius, that was really funny for see it xP.
