why did you post twice?

think a little..... jump on the boxes. That took me like 2 hours to figure out, I was so proud of myself when i did it though. You should try to do these things on your own though.

This, too, was annoyingly hard for me. Find a square room, and ... use your ingenuity.

Just keep in mind your ingenuity has everything to do with your Jump button.
