House rules

• ←/→ or A/D to run · Space to jump · P pause · R restart.
• Speed is height. The faster you're moving when you jump, the higher you fly.
• Walls bounce. Momentum is kept — zigzag to build monster jumps.
• Skip 2+ shelves in one jump to start a chain. Keep skipping to keep it alive — chains are where the score is.
• The garbage collector rises from below, and it only gets faster. Deallocated = dead.
• Every 10th shelf is a milestone rack. How many U can you climb?
