On level 5, at the first pillar with arrows you need to just jump through a portal that will take you to the other side (the first red switch) and as you jump through shoot another portal at the SAME SPOT so the pig also joins you on that side. After that the rest is easy, just remember that your pig isn't guided by the arrows (your portals will take him straight to you, but if you went through them they would take you right back to him).
Repetitive, especially if your 'survivors' don't survive more than a few days and you are left with two pistols, a bow, and a cat. And while that would be an exciting MacGuyer episode, it makes for a hollow game.
There is no ending. Beat with a second computer running on autopilot while I did real work, got my hard badge, 1/5'd and I'm outta here. This game is a major money grab, and that's two badge runs in a row on pay-to-win. We expect better Kong.
Attention Kong Admins: This game has been public for several days. As a Nerdook game, that is well past the 20-minutes-or-less mark at which point you should have added badges. Hop to.
