Place the order
Type it or say it. "Asteroids but the ship is a shopping cart." The foreman asks at most two questions, then sends it down the line.
Watch the line
The code streams onto the bench while it is written. Thirty seconds, give or take. Then it runs on the test rig: keyboard, mouse, score, lives, game over.
Open the hood
Change a number, change a rule, press Run. Break it and the foreman will fix the fault without undoing your edit. Good helpers go in the parts bin for the next build.
What runs here
Plain JavaScript on a canvas, sealed in a frame with no network. Cartoon action, real difficulty. No gore, no hate, nothing you would not show a parent.
What is stored
Right now: your builds stay in this browser, on this device. Nothing about you is sent anywhere. Accounts and a public shelf are coming for 13+ builders.
Who it is for
Thirteen and up. If you are younger, Maple's World has a game maker built for you.
