Fun concept with neat execution! I like using the text on top to help divide your attention as things start to get going faster, as well as giving you something to do while waiting on the earlier parts.
It'd be nice if the difficulty scaled a bit to make the earlier parts go faster if you're solving them quickly as I found myself getting a little bored waiting for the dude to make his way close enough to the next hacking puzzle, but the later parts of the game get appreciably hectic!
