Official text says climb to reach new areas, then train Speed. Recorded climbs find a spot, go as far as Speed and stamina allow, steal, and jump home. Which button starts a climb is not shown. Read the prompt on your first trip.
There is no height meter and no published Speed gate for any floor.
- Train. One run went from 4,000 to about 15,000 before heading up.
- Step onto a visible climb spot.
- Stop when energy dies. Empty energy is a crawl. Buy stamina, or drop to the shop and buy power, then go again.
- Steal and jump down on purpose.
Floors announce themselves: dinosaur area, Jungle, Lava, Ocean, and Welcome to Winter. The summit is the highest confirmed point. One player reached it after an x10 multiplier and said the trip took under an hour of play. Nothing shows a layer above it.
Climbs fail for stamina, a Speed ceiling (about 100,000 was called much farther), short clocks (about one minute per climb, 2–3 trips in a five-minute window), Jungle edges, and Winter draining health and Speed. Falls in two sessions cost time. They were not shown destroying items. That is not a tested rule.
Rebirth is stated to let you climb farther and it wipes Speed. Rebuild before the next tall attempt. If the next floor stays out of reach, train instead of retrying an empty bar. Success looks like a banner or new ground, not a key.
