the level 16 is quite easy, you need to shoot the boxes to the wall on the left with moderate strenght, and take it with the under machine, get one box at the time, if another one come on the upper machine don't care about it
GiGa, the idle mode, is if you are not there and the game is opened, it collect the bar, anti-idle, you need to move or do something on the screen to gain it
aw... i was happy to see the number two, but the lack of history (Like him talking when finishing a mission) has made me a little outch, but anyway, great game 5/5 (No need to rate this comment it's only for information purpose)
Just keep the "Up" arrow pressed!
