Hi, I have a small problem.
IN the first level, how do you climb up ladders?
I know it sounds like a simple and dumb question, but i tried looking in the controls for it and didnt see anything, so if anyone could help, I'd greatly appreciate it.

Yeah, jumping next to ladders works, it just took me like 5 jumps to get up one. It seems so obvious now I can't believe I missed it! Well thanks for you help

Just HOLD the jump/crouch button to climb up and down without pressing more times. :)

Yep like the last poster said, that is how you do it properly (holding the jump button instead of pressing it repeatedly). The first time I played the game I was frustrated trying to climb ladders by hitting jump a thousand times and eventually, very slowly, i would make it up them. I figured it was a bug for sure and it never occurred to me to hold it for the longest time!
