I don't enjoy this episode at all possibly because there's no clear mission as to what I have to accomplish. It's more about exploring around the city and solving puzzles whenever I encounter them. Why would I bother unlocking a door to the satellite station and messing around with the equipment inside? I didn't get it until I found a microphone which allowed the alien to communicate with friends. And why would I pry a manhole cover? It's not because it's closed tight and I happened to find a tool to open it. The game should tell us that there's a shiny object underneath.
Thanks to the walk through, I didn't know I could click the "upward" (north) button twice to reach a locked satellite station. Also, I couldn't relate the EIB clue with a phone situated quite far away.
There's a clickable mail box that I could do nothing about it.
