How to play

Goal. Clear every floor of every stalk, left to right, and beat the boss at the top of the last stalk.

Climbing

  • Step on any open floor of the current stalk, in any order. Every floor of a stalk, good or bad, must be cleared before the next stalk opens.
  • A bug is beaten only when your strength is greater than its number, and a tie loses. Winning adds the bug's number to yours.
  • Nectar adds, honey multiplies, a thorn subtracts (you are lost if it would take you to zero) and mildew halves you, rounding down.
Order is the puzzle. You have 5 and a bug of 5 waits with a nectar of +3. The bug first ties and loses. Take the nectar to become 8, beat the bug for 13, then the boss of 12 falls.

Tricky floors and help

  • A grower (12 ↑2) gains its growth after every step you take, so face it early. A shielded bug counts double while another bug is left on its stalk.
  • A padlocked leaf opens once the floor holding its key is cleared. The boss waits until every other floor of its stalk is cleared.
  • Three stars for the best final strength anyone can reach, two from 80% of it. Hint shows the next floor of a best line, or says none is left; Undo takes steps back, even after a loss. 60 levels in five tiers.
