Collecting lights in a dark cyberpunk city is plunged into eternal darkness it as being on a planet without sun orbiting. At the beginning it is fine, but from level 6 the difficulty curve increases too abruptly, since it's due to the fact that the climbing platforms catch you by surprise, which makes it easier to fall back to the beginning, and also the character jumps are inaccurate for those short platforms.
Conclusion: Level 6, 8 or other are maybe a "impossible crap".
