Field notes
Each stage starts with partly written JavaScript; phone users can enter code through command chips. The page says code runs in a browser sandbox against hidden inputs, with three stars tied to an efficient solution’s Big-O. Off-By-One Imp, Infinite Looper, Null Wraith, and Lag Goblins turn common errors into enemies with plain-language hints. Cross-device accounts, Python, an Android app, and premium worlds are listed as forthcoming.
