So the entire physics engine is redone and running better than ever. It's smoother, it processes more efficiently, and best of all there's less hit Tests, so that means the game spends less time processing everything.

All of it helps tremendously in the game play department, things like, you actually land on floors, rather than sometimes you land a little inside of them. The same goes for walls and cielings. you will always collide perfectly with all surfaces, and it makes the game a lot less jumpy.
Where am I going from here?
well, I have to redesign the levels a bit, this isn't anything really serious, though it will take some work.
I have to do this because the new engine doesn't run the best with the existing levels. for the most part it's ok, but there's places where levels are now impossible, or to easy. (for example, Canthos can now climb UP walls, as well as slide down them, forcing me to rethink a bit how things are mapped out)

As well as the redesigning, I'm implementing a bit of "new technology" into the game that simplifies objects that are off-screen. This means those fans in sun-loft will stop spinning if your not looking at them, meaning flash is no longer animating it, and there's no longer any hit tests or code to worry about in it till you get close enough.
This means that the game can now run about 50 times better than it did before, in fact you may not notice any slowdown at all, unless your computer is absolute CRAP.

that's all for Canthos news for now folks, stay tuned.
