Several of the games mechanics actually change with the video quality, especially when trying to run across multiple surfaces without jumping. In fact, level 6 is impossible on low quality, for obvious reasons.
Besides that, "thinking outside the box" roughly translates to looking for the letter in parentheses or word in all caps. Combine that with the lackluster controls and it becomes a relatively disappointing blend of I wanna be the guy and the impossible quiz. I appreciated the atmosphere of it, but it feels incredibly unrefined.
