Each courier starts on a platform with coloured parcels in the satchel and launches on its beat (the number on its tag). Couriers ride cables downhill only, one platform at a time, climb ladders (slowly) and walk rope bridges. Arriving at a treehouse drops every parcel of its colour. A courier stops when its satchel is empty or no line leaves its platform. Deliver every parcel before the rain at the end of the timeline.
Pulleys: tap a junction platform to point its arrow at the next line. Striped flip pulleys swap sides after every courier that leaves. Pulleys are free.
Pieces (each costs a point): a rope bridge fills a dotted bridge gap; a brake pad holds every courier one extra beat on that cable; a banana on a platform is picked up by the first courier to arrive there.
Hazards, all visible from the start: the howler monkey swings its dotted loop one platform per beat and takes a parcel from any courier it meets (a banana instead, if the courier carries one). Two couriers on the same cable at once bump and each drops a parcel. A toucan sits on its perch on a rhythm and nobody can launch from there while it sits. During a gust (blue on the timeline) a swaying cable lands on its other platform.
Press Go and watch. Drag the timeline to see any beat; faint lines show where your plan sends each courier. Score = pieces placed (lower is better): deliver everything for bronze, then silver and gold. A miss shows which parcels arrived. Ghost shows your best plan, Hint sets one pulley or piece that works.
