Marshmallow World

The pitch

The Chocolate Monster has locked the marshmallow family in cages - and only you can save them! Shoot sticky webs and climb up through 100 levels of candy bars: conveyors, ice, seesaws, fireballs, melting and crumbling platforms. Solve tricky puzzles to free your friends, collect strawberries, dress up your marshmallow with hats and outfits, and beat the Chocolate Monster boss in every world. A cute climbing adventure for all ages.

Controls & how it runs

Mobile: slide your finger left or right to move. Swipe up to shoot a web and climb to the next bar. PC: use A / D or the arrow keys to move. Press W, Up arrow or Space to shoot a web and climb. Reach the top before the hot chocolate catches you, then solve the puzzle to free the trapped marshmallows.

Getting a run going takes exactly one press: Press start, up top, and the game boots inside this page — nothing downloads in the background and no form wants your details before the first jump. The cabinet is drawn for a flexible screen and listens to mouse, keyboard or touch, whichever the game prefers. It reshapes itself for tall and wide screens alike, so phone, tablet and desktop all get the full picture. Given a fullscreen button, use it — scores look better at full size, that's just science.

Pro tips for arcade cabinets

• Treat your first run as a scouting mission. Arcade cabinets hide their cruelty in the second minute, not the first — learn where the difficulty spikes before you start chasing numbers.
• Small scores compound. Grab the easy pickups on every pass instead of gambling the whole run on one heroic line; heroes respawn, banked points don't evaporate.
• Watch the edges of the screen. In classic arcade design the next problem almost always enters from somewhere you weren't looking — build the habit of scanning the borders.
