To make it clear:
- Its only a developer version, with not much detail and light adjustment, no cameras, sounds or observaton rooms
- Rooms will look more clear, hints/tips are not included yet
- Last room will not be the last room
- Added a spawn-timer to the box dropper, so if all 4 box has been destroyed in the same time, they will respawn one by one every 2 second
- If the portal-from-a-portal room is too hard (must be too quick for an "average" difficulty level) I'll lengthen it (the room), send feedbacks pls!
- There will be 1 more big room with 5-6 small individual puzzle.
- Overall I rate this map's difficulty as "not too hard". If you want better (harder) puzzles, map #4 and #5 will be your friend

Whats new:
2008.01.01
- fixed the chemical dmg, the last room's box respawn, and blocked the way to the comp.cube in the first room and increased the button's trigger size above the door.
- Forgot to add prtal bumper to the end of the chemical room, added
- Will add a cube-sensitive triggen after the first big room so players cant stuck after removing the CC from the button and jumping back to the first room.
- decreased the time by 2.5 sec in the last room. (I can even do it if I decrease it by 1 more)
- here are 3 video that I made how I want the player to solve the first, chemical and last room, let me know if you find a workaround solution (spoiler):

- Its a pretty early version, I dont wanted to post it but if I get too drunk tonight, I'll not continue it till next year 

Please post opinions, feedbacks, bugs, possible exploits (shortcuts)
Hint:
- To get through the chemical room, you must shot a portal and move back before the new portal link is established, or it will push you into the poison.
