Definitely get the AI and collision working first, and then the ICE editor last, because you need a real game for the level editor. Also, this is sounding amazing! So much further than I am... I would love to see some screenshots if possible! Good luck on finishing in time!
No, I mean that the ICE editor is already basically done. I just did that during my free time when I didn't have access to a computer, so it didn't take up any C time. I'll post screenshots in a few minutes (you can see them in the latest screenshot section in the original post).
