Hi Lukas!
Just completed your brilliant puzzle!

Though I'm not sure if I solved it the way you intended.
As for the glitch. It's the same one that makes boxes appear invisible in the water.
There are many objects you can place parallel on the left side (example: a flame) that will trigger it.
I noticed my traffic light signal in your level, and a very clever variation on the ice path trick.
I did not need one of the trampolines, or the ice patch near the three spheres.
That's why I suspect my solution was slightly different.
I am very honored to have this dedicated to me.
It's one of the best mental workouts I've had in a long time!
Thanks!!!
Mark
