need one player to play cooperative and do archivements.

Local co-op isn't enough. With an uptade ONLINE co-op without splitscreen should be added to the game. Servers isn't necessary. Players could open local hosts ( with hamachi and stuff or LAN ). We must be able to play with our friends in our homes. Who is with me ???...

Can't find anything, I'm from Australia and I can't install this game or add it to my library, can someone tell me why?

Is best friends forever possible to complete alone, since it's local coop? Can you 100% this game all by yourself? "Faking" being both coop players yourself? I don't mean input wise, say keyboard mouse & controller, I mean, do both "players" or in this case 1 player need to act at the same time, which would be pretty much impossible alone....

Jumping doesn't always jump, and for levels relying heavily on jumping off platforms it's really annoying. Any fix for this? *edit* I just noticed the last update was 5 months ago... i hold no hope on this getting fixed, great.
