You start in tomoLaSiDo's room where is cheerful piano music encouraging you to find six key parts and many electronic components. Bathroom door in Neat Escape's apartment is locked, but you are lucky - just look around - yes, there is fantastic view at a lake but that's not what I mean - look again - yes! There are hints and also a place where to input some numbers. You will get out after all, relaxed and refreshed, and prepared for long journey out of 4399's cellar jail cell (new Chinese developer after a long time)!
Have a good time and enjoy!
