One Line throws you into a tense doodle-puzzle where your pencil is the only thing between a helpless guy and a very bad day. One stroke. Big stakes. Your pencil are his shield. Sketch a single, unbroken line to block bombs, tip landmines out of reach, cage furious bee hives, deflect bullets from hired assassins, and keep the sky from dumping a cold, heavy rain right on his head. Sometimes it's a neat arc, sometimes a weird squiggle if it works, it works. Physics bite back here. Weight, balance, gravity every wobble matters. A clever curl can turn into a ramp; a chunky block might topple at the worst moment. Each level bring a new twist: angry giants, chain reactions, tight spaces, unexpected angles. You'll poke at the edges of your imagination, then push straight past them, all through simple, satisfying drawing that just feels right. Think one line can stop a disaster? Prove it: grab the pencil and play now!
