Great level! I didn't see the designed solution quick. In fact, I solved it first using an exploit but after thinking a while I found it. Very clever, thanks! Spoiler: Shortcut Using Air Tripping exploit you can avoid 50% of the level but... the designed solution is really better.
Well that was much harder than yesterday but worthy of 5 stars. I was trying to get the Rs to do the work and then realized. Very clever!! Thanks
