With the demo :
Bugs :
A) Seems that you can push people around - literally, when testing a level, if you only shoot them just a little.
B) The German with the bazooka obviously has a deathwish - he fires the weapon and blows himself up.
C) Slows down a lot on my development machine (2.4Ghz Intel Geforc4 mx), whenever there is at least one baddie visible.
D) Very slow in re-loading map after finishing with testing a level.
Other :
A) Trying to position anything in the top-left corner of the map window is very difficult as you cant see the exact position.
B) Annoying having to press the cancel button in the entity/prefab/segment etc menu list before being able to select another tab.
C) Progress details needed to portal generation and various other bits when floor optimisation is active - otherwise people will think the level generator has crashed.
D) Light from inside a door is visible around the door frame. Examine the door with the included level.
