This was fun! I liked the mechanic of leaving the robot buddies behind as guides and markers to help you when the lights shut off, and the platforming was simple, but still fun, with the darkness adding a good bit of challenge to it. I had initially thought that the robot's colors would make them do different things, but when I realized that wasn't the case I was able to use the different colors to mark out different things, like blue for being at the edge of a pit, and green being safe. I agree with another comment that adding different effects could have been cool, and that the art styles clashed a little bit due to the assets used, but it wasn't so jarring that I was really paying attention after the cutscene ended.
I'm not sure whether this was just on my end or not, but there had been no music playing during the cutscene. Let me know if it just glitched out for me! I think music there would have been nice, and also that an ending cutscene could have been good as well (again, if there was supposed to be one and it just glitched out for me, do let me know!)
Overall, it was a nice little platformer, and I had a good time. Good job!
