I hate the bonus system. Why would I need auto pilot (or even worse - slow down) after the very first ball? I guess I suck at it (my best is 47k) but I don't really believe you can make 100k with just jumping on the keyboard and not being lucky enough to be awarded the right power ups at the right moment.
I was a bit disappointed. The game is easy, you spend way too much time in that virtual reality and connecting to the system demand you to plug your connection pod every single time (it could be automatic). The story develops in an interesting way, but the overall experience for me was quite boring.
