thanks, the levels were a bit last minute, running out of time. Out of curiosity, did you complete level 10?
Yeah I did. It took a few tries as it was one of the harder ones. But I did just skip around on levels. To be honest it wasn't entirely clear that the different pieces were. I didn't even notice one was switching the tracks as I could barely make out the little switch on it. I guess that is what I get for jumping around in the order of puzzles.
