This is an original browser block world, not the Roblox engine. Forge supports numeric variables, arithmetic, comparisons, if/else, bounded numeric for loops, zero-argument functions, platform(x,y,width), coin(x,y), onCoin() and print(). One statement per line; use end to close blocks. No tables, strings, while loops, network, files or arbitrary JavaScript. Code runs in a disposable worker with 5,000 execution steps, 1,000 objects and a 300 ms wall-clock limit. Values are bounded to ±10,000. Export provides genuine Luau starter scripts; your entire browser world is not converted automatically. Saves stay in this browser; no account or cloud sync.
