Yeah, well at least all the necessary files were there so with some knowledge on how the Mac apps are structured, it wasn't that hard to get it working. And anyone else facing the same can just slap those lines to terminal and voila.
Oh damn, I actually did get the crate with the jump dude. On my previous try I though jumping through the enemies would be too difficult so I guess I for some reason on my next try built the ladder up there and still didn't even use the hammer guy. But now looking at the pic, can you really jump from the mid platform all the way up there? I looks too high to me right now.
Btw, saw someone else too use the exact same environment tile set so I guess that half was the non you part. So you drew and animated the character sprites yourself? They looked awesome.
