I was not able to reach level 2 or above... The level select is a mini game in it self which is very cool, just difficult. I did enjoy the parts I got to play.
Sorry about that. Some people forget the grapple mechanic and don't realize how to use it to proceed. I think other players are trying to jump when we consider them to already be in the air. Demo of getting there
Move left into the upwards ramp, (hold) jump, move right, grapple up-right (w + d)
