I got really sucked into the hacking minigame and kind of forgot the rest of the game until I had completed that section. I did not really get the connection to Erosion. If I had to really go on a reach I'd say the Erosion of the computers by infecting them? But that feels really weak so I doubt it was the intended connection to the theme. I'm also not entirely sure what secondary theme was used. I'm assuming mining for resources with the Computer game. But I don't know for sure. The games it's self seemed pretty well polished but things seemed a little disjointed as far as connection to the themes go for me.
