Yes hidden, but otherwise not surprising. And it's all discoverable, partially because you have no other choice but to sent R somewhere as there's just no other option. Really liked exploring this beautiful level, and the nice mechanisms.
Great level! It was weird and unique. I liked both contraptions and had no idea what they were going to do until they engaged. Finding the order of the balls was just the right amount of logic. I didn't think it was too hidden, I thought things were concealed just enough so that it wasn't too easy, but still let you figure out what went wrong with the order (like the R in the tunnel getting the star). It took me a few tries to get the win. I first thought the win would need B or R together, but the second time I got to the end I tried the actual solution, and missed my ride, but it was satisfying to find the complete path. Nice work! I also enjoyed the visual design of the level.
