On stage 32 Backtrack, what the thing that blocking R but B can go through when R not blocking the way? I try to recreate it but can't figure out what inside that tunnel, it's too dark to see
It's a stone pillar in there. R and L bots don't walk on them (except in special cases). If you are interested in learning more R/L bot behaviors, look here: R/L bot Behavior Tutorial
