The following description is from "About" section of the pull-down menu "Help" of the Windows version of the software:
"MODERN LANGUAGE · FAST PROGRAMMING
A development environment inspired by classic QBasic / GW-BASIC created for demo-scene effects, retro graphics, animations, and learning programming in the 80s/90s style.
Features full syntax highlighting, a step-debugger, SpriteShop, Sound Tracker, SFX Generator, 2D graphics and Web Audio."
The name of the development tool is basicFusion and it is also the name of the BASIC dialect. The tool is impressive. I downloaded the Windows version to try. I also tried the browser version.
