Flat Menu UI

Flat my project is updated!!
I improve the usability to change "Room" and "Lounge".

Room: Chating space with co-worker anonymously.
Lounge: Chating space with same industry people anonymously.

Do you know Flat?? If you don't please check flat.place !!
Flat lets you start conversations (about anything!) on flat level basis with your co-workers while remaining completely anonymous without names, titles, or hierarchy
