I hate to be this guy (I really do), but maybe lower the difficulty settings?
...I don't know how much the team gets to play long games... I can't imagine your testers do because they're constantly wiping and starting over to test, and you devs have been some busy damn beavers, and you've said yourself this is YOUR longest game (which is great!), so I guess my question is, *shouldn't* they be getting rekt? Isn't learning what works and what doesn't part of the fun? You said so yourself when people were giving you gameplay tips...
The wolf thing I get... It happens, rarely, but it happens... I don't think you should change it, but I get it... But making a hoe (your argument) is the same as making any other tool... All of them, in fact... and the rest of farming is just common sense, AND already works that way in Minecraft... And I've *never* built a farm in game, but recognize the import of keeping it complex.
...am curious what the technical issue is on run speeds though.
