Controls: Arrow keys/WASD to move and jump. Press Action (Space/S) to flip gravity! The world flips — ceiling becomes floor!
Mechanics: Gravity flip has 0.5s cooldown. Blue = solid only in normal gravity (pass-through when flipped). Orange = solid only in flipped gravity. Green = always solid. Moving platforms work in both states.
Goal: Collect all keys to unlock the exit door. Watch for spike pairs — floor spikes and ceiling spikes swap positions!
Power-ups: Gravity Anchor = no flip penalty for 10s. Double Jump = extra mid-air jump.
Score: Level x keys collected x 100!
