Wow, coming out of Velocity Noodle hot. I love it. This is a winner dude. The presentation is excellent. The game feels great to play, and the concept of "connect anything" is really exciting. I think there is so much potential there.
Only real feedback, is to perhaps make the hacking part a little more smooth feeling to control. That will help keep the pace of the game up. For instance, when you go into hacking mode, the actual click target for objects is small. That makes sense for enemies where there is a skill component that is enjoyable (missing is a mistake, then finally hitting feels great). Missing the click on a hack target just feels tedious. Perhaps instead of well-defined click targets, in hacking mode, there could be some sort of "nearest to mouse" hueristic, with a boundary of course. That would be much more conducive to quickly going "pause -> click -> click -> click -> unpause -> boom", which I think is really the core of the game.
I think going over the top with highlighting the hackable targets in hack-mode is also a good idea. When you pause, you have a cool effect. But the actual hackable targets are a tad bit lost in there.
Oh yeah, and the visible sightlines on the enemies is excellent. I think you have a great design sensibility, and that's a good example of it. You've already found the fun with this game, it's seriously cool. Keep it up.
