I can't figure out how to incorporate the yellow spire into a line of 4. The only way it would work is if I can also get the orange spire into H8. HOWEVER, I don't think this is possible because of the blocks.
Any advice?
Here's my visualization I made while trying to solve the level. (the "x" is for spots that are impossible to put a spire)
