Thanks for playing, I'm glad you enjoyed it! In level 10 there is a light movable in the X axis at the start, followed by another which you can drag around in the Y axis
I tried moving it last time but i just couldnt, having seen what u wrote i think there might be an issue with the collider there, its up in the joint while all others are on the actual lamp.
Off i go to level 11, thank god for saving progress :)
