Use the mouse to click, or tap (mobile friendly), press space, or use the arrow keys to jump. Also this level is probably a low-end harder level at best. I thought it was extremely hard a few years ago, but several users are saying it's too easy. Sorry bout that.
MASSIVE UPDATE: Like I did with the 1st level, I decided to go in and edit this level too. It looked like a disaster before, but now it has a different cube, and a MUCH BETTER LOOKING THUMBNAIL! Credits to SuperiorGaming901 for the original. Very much like the first level, it won't show up anymore because the original is gone now. His account is gone now too. (RIP Dude...)
