Here are my tips for hard bage :) TIP 1 Your main problem is the 2nd level(blue camera),so keep your eye on that level till you reach level 4.If you try to keep an eye to all levels brain will get confused on second level and get informations about it wrong.In the other hand brain seems to react easy to other levels because they are not too complicated.TIP 2 when you reach level 4 keep an eye on 2nd(blue) and 4th(purple) level.Still most of your attention on 2nd.Don't use both WASD and SPACE use SPACE only when needed and let WASD.When you don't need to fly with SPACE fast use WASD to take the boxes fast.Still all your attention on 2nd level thought.Hope that helped(I did it with this tricks) :)
This game is more about luck.This is how it works.If God likes you and sends you spikey and small ball you won the badge.If God hates you and sends you normal and big ball you are screwd :P
