It is the first in a series of 7 to 10 (don't know exactly yet) I am planning to do in order to learn hammer.
This one focuses on buttons and doors, with simple flings.
It is probably not really fun or challenging, but remember this is both my first map and room 1 in the series. The rooms will follow a progressive difficulty curve.
The series takes place in aperture science secondary labs. In this lab, GlaDos "daughter" Glados II begins her own experiments.
I am according lot of thought in creating new sarcastic lines for this junior sadistic AI. 
Planned improvements (any advice for making those will be gladly appreciated) :
-Customize the "01" sign
-Import a custom overlay to make the "aperture laboratories" logo on the black wall white.
-Import custom sounds for GlaDos II speak.
- Slight visual improvements
- correct the tubes in the pit (I know they are wrong, but I was eager to get opinions before going further).
-Listen to your advices 

okay, looking forward to the other challenges.
I'll just post any little idea I get here. You may do with them whatever you want.
