Scramble! Doodle Flyer is cleared for take-off.

It's a WW2 air combat game in a hand-drawn style that runs right in your browser: the planes, the ships, the flak and the clouds are all wobbly ink lines on cream sketch paper. The lines even boil gently, like an old flip-book. You'll find it at flyer.tripgeo.com, with nothing to install.

Watch the trailer

Here's a one-minute taster. Every shot is real in-game footage, rendered straight out of the game engine, and the explosions you hear are the game's own.

Ten missions, 1940 to 1945

The campaign starts gently with First Solo: take off, fly through the hoops, hit a few targets and land without bending anything. Then the war begins in earnest. In Their Finest Hour it's September 1940 and the bombers are coming over the Channel coast, so meet the escorts head-on and break up the raids before they reach their targets. In Hunt the Vanguard you head out over the open Pacific to make torpedo runs against a whole task force, which, as the picture above shows, does not always end well for the task force.

In Red Beach Operation Sea Lion has gone ahead, and it's up to you to throw the invasion back into the sea. Iron Fjord sends you hunting a convoy in Norway, low between the cliffs while the flak gunners do their best. Front Line holds three waves of armour, flak and fighters in Normandy, the tanks are hiding in the city streets in Concrete Jungle, and in Steel Tide you escort an armoured column through the ambushes of the Ardennes.

And in Black Rain you go out at night to bomb a desert refinery, where the searchlights sweep the sky and, if your aim is good, the oil tanks go up one after another.

Look closely at the missions screen and you'll also find a link to some Experimental Bonus Levels. We're not saying anything about what's in there, except that the label says unstable.

Five aircraft and a rescue at sea

Your hangar holds five aircraft: the Sparrowhawk fighter-bomber, the Mule twin-engine attack aircraft, the Dray medium bomber, the Harpoon carrier torpedo bomber and the Pelican flying boat. Between them they carry machine guns, rockets, bombs and torpedoes. The Pelican gets the kindest job in the war. In Pelican Patrol you fly over the islands with a pilot somewhere in the water below, and it's up to you to land on the sea and bring them home.

There are three difficulties. Milk Run gives you unlimited spare planes. Veteran gives you three. Meat Grinder also gives you three, then sharpens the flak gunners' aim and sends the enemy fighters after you far more often. Doodle Flyer plays in a desktop browser with a keyboard and mouse, and it's built with Three.js and Claude.
