Well, that update was easy.
Update
I updated it to Axe 4.0 by swapping out my hex algorithm for the official Axe 0.1.4 commands.

Sorry to leave you guys hanging for so long.

Update
New in this version:
(Almost) finished the physics engine
Finished the graphics engine
Fixed the MirageOS glitch

Things to point out:
The physics engine is running with multiple objects being updated, something that was very hard to do
The character can't go through walls and floors (that took me a while)

Things to do:
Remove all the HL2 specific code from the game and post a beta of Source TI
Finish physics engine (needs boyancy and collisions between objects)

There will be many tiles, not just plain black.  I just want to finish the engine first.
Also, you say it runs fast.  I use a timer that slows it down drastically.  It is running at 1/10th what it could be running at.

I don't think I will do scrolling.
The engine isn't set up to handle that kind of thing.
Also, like I mentioned before, the engine adapts.  As more objects are added, it will begin to run at 1/9th, and 1/8th, and 1/7th, ect.

Yeah, I've never liked that.  Every object takes 13 bytes of memory to manage, which allows for a max of 53 objects in the physics engine at a time.

Oh yeah.

does axe have any timer commands?  If it does, you could use a timer keep the framerate constant rather than adjusting the speed at which it runs.

@Will, Axe does not have timer commands, and if it did I don't want to lose compatability.
