A fast-paced vertical platformer right in your browser. Climb procedural towers, dodge hazards, chase your high score — no installs, no servers, no waiting.
Click the icon or press Alt+Shift+J and you're climbing. Every run is procedurally generated — different platforms, different hazards, different strategies.
Every run builds a unique tower — 5 platform types, wind hazards, and power-ups are placed dynamically so no two climbs feel the same.
Dynamic wind pushes you left or right unpredictably. Adds challenge at higher altitudes and forces you to adapt your jumps mid-air.
Collect Double Jump for an extra mid-air boost or Magnet Landing to snap onto nearby platforms. Both spawn along the tower as you climb.
Score equals height plus combo multiplier plus clean-landing bonuses. Chain perfect landings for massive combos and leaderboard domination.
First-time players get a step-by-step tutorial that teaches controls, platform types, and scoring. Skip anytime if you already know the ropes.
Remap left, right, and jump to any keys you prefer. Your keybinding config is saved locally and persists across sessions.
Each platform behaves differently — master them all to reach the top.
Push higher, unlock more. Every milestone rewards you with cosmetic unlocks and new characters.
Progressive difficulty from beginner towers to extreme endgame. Each level has a target height and star thresholds to earn.
Height milestones, combo streaks, clean landings, run counts, and score targets — all tracked and rewarded with cosmetic unlocks.
Jumper, Frost, Ember, Phantom, Golden, Void, and Titan. Each with unique skin color and trail effects, unlocked via achievements.
Top 20 all-time scores and your 10 most recent runs with detailed stats — height, max combo, clean landings, and bonus points.
Same procedural seed for everyone each day. Compare your best daily run with friends on the exact same tower layout.
Share a seed code so friends play the exact same tower. Head-to-head comparison on identical procedural layouts.
