Really interesting idea, the game is fun and challenging, sound and art simlpe but they fit the game perfectly. But, i think that the most challenging in the game is to try to hack the most as you and not to just fall, so I think that it would be interesting if the points were based on hacking it and maybe getting extra points on certain combination, but the power up idea is really cool too.
Overall, fun game, challeging if a good difficult level. Keep up the good work! Congrats!
