Retro Level Editor ships live playtest, HTML export

This is the kind of narrow, opinionated tool that actually gets used: one screen for building, one click for testing, one file for shipping.

• –Live playtest inside the editor removes the usual build-test loop that slows down level design
• –Single-file HTML export is the right constraint for jams, demos, and lightweight web games
• –Tileset import and layered painting make it flexible enough for real projects without turning into a full engine
• –The product feels more like a practical workflow tool than a toy editor, which is usually the difference between “cool demo” and “kept in bookmarks”
