Overall a great game and fits the theme perfectly!
Game Design: Pretty solid! The first area had a great atmosphere to it and the controls were tight apart from the spinning thing you mentioned already.
Fun: Very fun to play. The parkour / platforming is very well designed; though the area where the "lights turn on" could do with some checkpoints (I wasn't able to beat it :'( )
Innovation: Had some cool ideas and used them well. Not much else to say.
Theme: Perfect. The theme is captured expertly in the style and gameplay.
Graphics: I like the minimalist style of the game and it is used to create illusions in places very carefully, but in the second platforming section, it can be hard to tell when you're moving. Perhaps a lighter colour on the top of platforms would have worked better.
Audio: The lack of audio is effective here, though some soft ambient music would really lift this game.
This is a great game and I look forward to playing more of your games in the future : )
