This spot really ticked me off though: I bothered to haul around those brown boxes as a possible way to do things differently, but you take them away here when the next scene loads. I cursed you quite a bit there! If you planned on taking them away, then don't let me carry them through all the previous fizzlers.

• the non-hurting goo which was already mentioned in this topic
• door frame sticking out of the wall in one of the chambers:
  
• I threw a camera instead of a companion cube into the incinerator (but cheated to do so just to see if there was a way to get to the cake)
• build your cubemaps before releasing (ask in the forums if it doesn't work for some reason)
• some parts of the mappack was with overused glados speech and some were too silent. Probably needs some balancing.
• soundscapes were missing. They are important to add some great atmosphere

I found 4 alternate paths (where you could choose your way), and 4 cakes. I haven't found any of the secret rooms "behind the wall plates" (seen from the training map).
I can't remember more things I had on my mind before, so... to sum up, I recommend this for you to play. Maybe it was too long, but you can overcome it if you play with breaks.

A secret/unique chamber by all means.
