YES WE ARE NOT DEAD! Sorry guys I had school and some other stuff, but we kept chugging away on the mod and we are starting to see the light at the end of the tunnel. I can't nail down a date, but we should be able to release in 2010.
We have added a large amount of new content and have even started adding in enemy AI. Figuring out the custom animations and AI tricks have taken considerable amounts of time, but we feel satisfied that we can deliver a pretty good experience.
Here are some new pics showing off a couple enemies and the gravity puzzles. Also both the creatures you see have some form of AI in order to follow the player and make decisions. It will never be exactly the same.
