I didn't think there would be so much going on in this game. Even though i've only cracked the surface its got me gripped.
I would say you could use a in-game instructions, like a manual on the desk. I forgot i had to press ENTER on the signal finder and was stuck for like 2 hours xD. I had to go back and quickly redo the tutorial to figure it out.
I don't know if videos are allowed but i made one.
