Wow it turns into neon blue far away and many spots of the castle have no interior which isn't what I expected. I can't go in certain parts of the castle.
TOOOORQUEEEEEE
Um no. I could make my own interior castle with areas you can fully go in.
Nope, Torque would screw you over due to the massive .dif file. Trust me, I tried to add more.
Oh, but in the final version there is a way to get into two massive rooms from the outside. (One is an easter egg.)
