FoldFling: Hinge Catapult

Fold down to charge. Flip open to fling.

FoldFling is a handmade paper-craft physics puzzle where your phone's hinge is the throwing arm. Press the top half down to wind up the catapult, snap it open to let go, and watch a cardboard castle fold, crumple and tumble.

Don't have a foldable? No problem. Drag back on the screen and release — every level plays the same on every iPhone.

HOW IT PLAYS
• Charge: half-fold your phone into laptop pose and press the top half down. The deeper you go, the harder the shot.
• Aim: slide a finger on the lower half to set the launch angle. A dotted arc previews the flight.
• Fling: flip the top half open fast and the paper ball flies. Close the phone at any time to pause.

PAPER WORLDS, MADE BY HAND
• 24 levels across 3 worlds: a sunny Morning Fold, a violet Dusk Crease, and the starry Starlit Pleats.
• Every castle is built from cardboard, paper bricks, wooden beams and folded platforms that really bend, crack and collapse.
• Knock every paperling off its perch using as few shots as you can. Earn up to three stars per level.

NEW TRICKS EVERY WORLD
• Tri-Star: tap in mid-air to split your shot three ways.
• Paper Bricks: sturdy boards that take real force to smash.
• Floating platforms, tall towers and tricky ledges that ask for a cleverer angle.

MADE TO FEEL GOOD
• Haptics build as you charge, then hit hard on release.
• A creaking catapult that changes pitch with power, crisp paper crunches, and a calm, looping soundtrack.
• Smooth, cheerful animation with chapter openers and a star-burst finale.

PLAYS GREAT ON EVERY IPHONE
• On iPhone Duo and other foldable iPhones, use the real hinge as the catapult arm. You can switch to touch controls in Settings whenever you like.
• On any other iPhone, drag to aim and release to launch. Same levels, same physics, same stars.
• Built for the fold: the game keeps everything clear of the crease, and picks up right where you left off when you open or close the phone.

FAIR AND SIMPLE
• The first 2 levels are free.
• One purchase unlocks all 24 levels forever. No subscriptions, no ads, no energy timers.
• Game Center leaderboards and achievements to chase your best scores.
• Optional gentle reminders when a new challenge is waiting. You choose whether to turn them on.

Whether you just unboxed a foldable and want something only it can do, or you want a cozy physics puzzle for a few minutes on the go, FoldFling is a small game with a big fold.
