Goal: descend an endless mine shaft as deep as you can —
the deeper you dig, the more floors you bank.
The squeeze
- A crushing ceiling slides down from above the whole run, bristling with spikes. It speeds up the deeper you go.
- Touch those spike tips and you are crushed — instant death, on the ground or mid-air, full health or not.
- Staying alive means keeping below it, which means keeping down.
The shaft
- You only move left and right — gravity does the rest. Bounce off the walls if you slide too hard.
- The shaft is lined with short floating shelves, one to three per row — weave through the open gaps between them to keep dropping.
- Spike shelves (bristling with pillards) drain your HP bar while you stand on them — at zero HP, you're paste. Landing on a normal shelf heals you back a little.
- Conveyor belts — the steel ones with amber chevrons — drag you sideways toward the walls while you ride them.
- Bounce pads — teal springs with up-arrows — sling you back up the shaft. Thrilling, right up until the ceiling reminds you which way is down.
