Fun game!
Couple notes:
* Hit detection is broken though and doesn't work most of the times on the first click.
* There's basically no way to loose when you're decent at the game. I get more and more bonus time and before I got bored I had like 200 seconds to spare so I just let it run out.
* You might want to introduce a mechanic to make it more difficult the longer the game goes (=> For example by making the hacks move quicker)
