About basicFusion
basicFusion v2.6.0

basicFusion is a small BASIC that runs in the browser, built for making retro-style games. You type a line, press run, and it happens straight away. There is nothing to install.

Made for everyone

It is easy to pick up, and there is enough here to finish a real game. Everyone starts the same way: an empty screen and a blank line.

Kids & first-timers

Your first program is one line: PRINT "HI", and it shows up on screen. Short enough for a ten-year-old to follow, but it is still real code underneath.

Hobbyists & retro lovers

If you miss the 80s and 90s demoscene, the pieces are all here: raster bars, chiptunes, pixel sprites, even a raycaster. The tools sit inside the editor.

Teachers & tinkerers

A whole class can work in the same browser tab. There is nothing to install and not much to break. Share a link and everyone runs the same thing.

Everything in one tab

You do not need separate apps for graphics, sound, levels or debugging. They are all part of the editor.

SpriteShop

Pixel-art editor with layers, undo and import/export.

Sound Tracker

Write chiptunes note by note in the browser.

SFX Generator

Zaps, jumps and explosions in a couple of clicks.

Tilemap Editor

Paint levels that plug straight into your code.

Font Editor

Draw your own bitmap fonts.

3D ModelShop

Build low-poly models for simple 3D scenes.

Step Debugger

Walk your program line by line and watch every variable.

2D + Web Audio

2D graphics and sound straight from BASIC, no libraries to wire up.

The language

basicFusion has its own dialect of BASIC. It reads more or less like plain English, which is half the point.

Nothing to download, nothing to configure. Open the page and you are already in the editor. Loops, graphics, sound and input are one keyword each, so most of your time goes into the game instead of the tooling.

When it is ready, you can export the same project to the web, Windows, Linux or Android.
