You posted your mechanism 30 min. before I posted this level. And I haven't made 8 levels in 30 minutes.
Nice level. Thanks! By the way, I didn't notice any exploit solving it, did I miss anything? Spoiler I forced R to climb the stairs and get on top of B. Then move B so R falls down and done.
Spoiler I repeated n times. There is no zap. I move B under the first stair, just turning around the corner three tiles (stair, grass, stair).
