I like the concept, and I think it would come out great with a bit more polish!
Here's some of my feedback:
Getting into the game is kind of hard, and it took me a few minutes to understand what I needed to do. It isn't immediately obvious that you need to defeat all of the hands before being able to continue to the next level, especially because in your description you say that the player should avoid the yellow lights! There could be some visual indication if the player can move on, such as a lock on the door or the door not being visible until the player can get through. I got to the door a couple of times and was confused when I couldn't move on.
Also it might be a good idea to have some sound effect and a brief pause when loading the next level. The first time I went through, since I wasn't sure if I could enter the door or not, I immediately fell to my death in the second level because my inputs carried over from the previous level.
I think it's not good that the game kicks you back to the first level if you lose. It makes getting back to the harder levels, on which you will lose a lot more, more frustrating than necessary.
The game looks great and the music choice is good. Hope you continue working on this, keep up the good work!
