PAPA CHOP!

❄ Frozen Forest: freeze the timer for 6s; branches still hurt.
🛡 Bark Shield: survive one branch collision within 15s.
⚡ Thunder Chop: summon one lightning strike after 1.8s, destroying 20 logs at once; time pauses during the summon.
💪 Papa Hulk: green, branch-proof ×2 for 10s; successful taps restore extra time.
👊 Papa Fury: turn red and muscular for 8s: tap for ×5 damage; dodge branches.
💰 Gold Rush: double points for 10s. Bonus points do not advance power pickups, axe upgrades or timer difficulty.

Random mystery powers start about 60 logs apart and become gradually rarer. No new pickup appears during an active power; chopping during it moves the next pickup back. Consecutive powers never repeat. Difficulty keeps scaling with logs chopped: denser branches, faster timer drain and rarer powers. From 350 logs, metal-banded tough logs need repeated taps on the same side, up to 11 hits. Every damaging hit adds time; Hulk and Thunder break tough logs directly; Fury deals 5 damage per tap.
