I can get behind that bump.
We've been lucky enough to have some familiar faces back to help us out recently.
We have been meeting weekly if not twice a week. In particular, we've been going over the various puzzles. Some have been simplified, some have some new steps, some are spiders now (

) , but overall it's feeling tighter.
Bugfixing never truly stops. >_> Minor things here and there in between some of the larger puzzle work.
We have a motion capture system; had we mentioned that before? It's pretty sweet.
We're going to use it to get through some "characters standing and talking" bits as well as our pair of LONG storyboarded sections. I'm a good animator but I'm SO glad we don't have to do everything by hand. We're planning our first proper mo-cap session within a couple weeks.
We're also looking into some Unity upgrade stuffs. We have a lot more experience with dynamic loading and such so the load times in TSL5 should be smooth as a silk scarf.
Stuff is happening guys!
