Office Escape: Stage 3

[Clouseau]

I'm stuck.

I've been to all the rooms except the one behind the double doors (is THAT my exit?) and I haven't been upstairs. In my inventory I have 4 blank notes, the note from the computer and 5 keys. There are still some hot spots that I can't do anything with such as the ceiling light in the kitchen, the big bottle in the board room and the video screen in the other board room. Any hints in order to continue would be helpful.

Combine all blank papers and go to the kitchen. Zoom on the light on the ceiling and use combined blank papers. I didn't find yet how to use the clue given.

A key under a tile in front of the TV set. Maybe the clue was leading to this place. It's confirmed ! The notes disappeared from the inventory

Giving up on this one. Can't find anything worth having

I have found the

silver key from under the tile

but I still cannot escape. I am missing

one of the 10 yellow keys. I'm wondering if that's the reason why I cannot escape the room

[Rexroth]

Out quickly - all without help except for the where to find the last key. Was looking around for cupboards with 8x5 draws how silly
Dubious about the advertising references here and sublime birthday wishes at the end but was overcome with good vibes when the disco music kicked in.
Thanks again escape girl!!
