Here's the changes:
-Added New GUIs so you may change GUI color, just copy and paste into main GUI folder (GUIs are themed after Main Cast, themes are divided by sub-folders, go into the .zip go into gui, copy files in the folder theme you want and paste into main gui folder) Default GUI is Pinkie Pie themed (cause it's the last one I tested)
-Fixed Dragon's Egg
-Added Creature Egg item
-Paintings! (Yup, they're probably bad though, but it's a first run)
-Modified Ghasts, Blazes, Silverfish, Sheep, Magma Slimes and Villagers
-Fixed Boss Meter
I dedicated all day to these updates (and some ponies when I got frustrated/needed ideas), so I hope you all like them!
I added an adf.ly to the downloads page on the mirror link, so if you want to support me (eating sure is nice, y'know), click on it and have a 5 second advert in exchange for the pack.
If you are having difficulty changing the theme of the gui, please let me know! I tried to make the process as painless as possible, but even I make a derp now and then.
Enjoy everypony! See you next update/bugfix/whatever!
