Every game on this page was made in Myth Engine, a game engine for Windows that makes 2D and 3D games with visual Logic, and JavaScript when you want it. Build one of these step by step, then make your own game and publish it.
With the headline, a silent film made in Myth Engine. First, a meadow room of Tetherwick is built in the Myth Engine editor, a time-lapse of real edits: the ground, the backdrop, the props, Bobbin and the beads. Play is pressed, and the room is the running game: Bobbin backflips onto a shelf and collects beads. Then Pitch Shot, Shatterfield, Crystal Cascade, Chain Reaction and Sky Ace.

Then build it.
Each game runs right here in your browser. Each comes with a step-by-step guide, a Starter Kit with every picture the game uses, and the finished project to open in Myth Engine. Every chapter ends with a game you can play and comes with its own finished project, so if yours goes a different way, you can open it and compare. You can follow every game guide in the free demo.

Chapter one:
a plane that flies.
Chapter one of the Pacific Wings guide, in five steps. The movement comes from Vertical Shooter Controls, ready-made Logic built into Myth Engine. Logic is Myth Engine’s visual blocks: Events and Actions you snap together. You can follow it in the free demo.
- 1Place the Fighter in the scene.
- 2Give it movement Logic.
- 3Set its movement values.
- 4Press Play.
- 5Take the controls. It flies.
Edited excerpts from the Pacific Wings guide, recorded in Myth Engine.
These blocks set how long Chess waits for Stockfish, the chess program behind the Computer, to find a hint.

Snap Events and Actions together: over 400 built-in Actions and over 100 Events. When you want more, write JavaScript in Monaco, the editor behind VS Code, with autocomplete for the whole engine API.Logic in the manual

Questions
Why pay for Myth Engine when free engines exist?
If you want to finish a whole game, Myth Engine gives you a route to one. A free engine gives you the tools; here, six step-by-step guides each build a complete game with you. You play it first, every chapter ends with a game you can play, and each chapter’s finished project is there if yours goes a different way. You can follow every game guide in the free demo. You build with visual Logic, from over 400 built-in Actions, and write JavaScript in Monaco when you want more. The full version adds publishing: one HTML file that anyone with a modern browser can play, a web folder, or desktop and mobile projects you build and sign. Sell what you make with no royalties. It’s $84.99 USD, once, with no subscription and no paid upgrades.
Do I need to know how to code?
Five of the six guides use no JavaScript. Chess adds a chess program, Stockfish, with two one-line Run Code steps; every chess rule is visual Logic.
What kinds of games can I make?
2D and 3D games. For platformers there’s the Platformer Editor, with movement presets for the hero and a check that searches each room for a route. Ready-made Logic such as Top-down Controls and Vertical Shooter Controls gets a game moving. For story games there’s branching dialogue in Classic RPG or Visual Novel style, cutscenes and illustrated books. In 3D you sculpt and paint terrain, scatter foliage, add water with waves and swimming, bake the lighting and bring in GLB and glTF models. Multiplayer is built in. Games run on Babylon.js, rendering with WebGPU by default and WebGL 2 as a fallback.
Can I sell what I make?
Yes. Games made with the full version can be sold, with no royalties, however much they earn. No Myth Engine account, device activation or online license check.
Is it still being updated?
Yes. New features arrive often, and every update is included. Install Myth Engine with the itch.io app and it keeps itself up to date.
What do I do after I download?
First, install and open Myth Engine. Then learn the workspace. Then pick a game guide and start its Chapter 1. It makes a new project and installs the guide’s Starter Kit, which the free demo can do.
Where do I get help?
Read the 146-page manual, or ask in the Myth Engine Discord (opens a new tab).
Latest update, 23 October 2026: one Camera for 2D and 3D Scenes, and Cameras that follow the player, with smoothing and a dead zone.

Tetherwick: Wrong Side Out
The meadow room in the film at the top of this page is from Tetherwick.
Every place in Tetherwick is woven cloth, with a right side and a wrong side. Bobbin slips through to the back of things to untie what the storm tied up.
Right side: the river is wet.
Chain Reaction
Feed a mouse some cheese. A ball trips a switch, a boxing glove sends the next ball flying, and the conveyor delivers the mouse.
