Write Python-like code. Solve puzzles. Guide Gizmo._

Nope. The early Bootcamp levels introduce programming concepts from scratch. If you can type, you can play. Experienced coders will find plenty to chew on later in Endurance and Puzzle modes.

It looks and feels just like Python — same syntax, same structure, same nomenclature. You get the constructs you'd actually reach for: functions and classes, loops and conditionals, lists, dicts, sets and tuples, list comprehensions, f-strings, and try/except error handling. Under the hood it's a custom interpreter we built from scratch, modeled on Python's behavior — so what you learn here transfers cleanly to the Python you'd write anywhere else; the runtime is just ours. Your scripts live as plain .py files, so your editor highlights them like any other Python.

Absolutely. Every script is a plain .py file on disk. Write it in the in-game editor, or open it in VS Code, PyCharm, or whatever you live in — with live reload, Gizmo picks up your changes the moment you save. Since the files are plain Python, your editor treats them like any other .py. And if you live in VS Code, we made a Droning On syntax-highlighting extension that adds highlighting and autocomplete for Gizmo's API — moves, turns, scans, and the enums.

Anyone who can read and think logically. There's no age gate on problem-solving.

It teaches real programming, but it's a game first. No quizzes, no grades, no "great job!" popups. You learn because the challenges demand it, not because we lecture you.

Every Bootcamp level has a built-in, three-tier hint system that you control. The first tier points at the concept, the second sketches the approach, the third shows a working solution — you decide how far to peel it back. Puzzle and Endurance have no hints; once you've graduated Bootcamp, you're on your own. You can always try Discord and see if anyone can help!

Three modes and a sandbox. Bootcamp is a 20-level campaign that ramps from your first move() up through functions, classes, and algorithms. Puzzle Mode is 13 standalone challenges that don't play by the usual rules. Endurance is procedurally generated and effectively endless — it scales until your code or your energy gives out, with global leaderboards on every stage. The Sandbox is there for free experimentation, plus there's a wardrobe of cosmetics to earn along the way.

Windows, macOS, and Linux — all via Steam. Wishlist now to get notified at launch.

Droning On uses decal rendering that requires Vulkan on Linux. If decals (Gizmo's face, the yellow hazard stripes in Sandbox) aren't showing, your system is falling back to OpenGL, which isn't supported. Update your graphics drivers — mesa on Intel/AMD, the proprietary driver on NVIDIA. If you're on Snap Steam, switch to the Steam .deb package or the Flatpak version for better native-game compatibility.

Leaderboard runs are submitted online, so a few things have to line up:

• You need an internet connection. Scores are uploaded through our servers, not written from your machine. Finish a run offline and the game keeps your best, then submits it automatically the moment you reconnect — usually within a minute, and you don't have to replay anything.
• Steam has to be signed in. Submissions are tied to your Steam identity. Playing in Steam's Offline Mode (or with Steam signed out) means a run can't be verified until you're back online.
• VAC and game bans can't post. Accounts with a VAC ban, or a game ban on Droning On, are blocked from the boards. That's by design and isn't something we can lift.
• Only your personal best shows. Each stage keeps your single best run, so a slower attempt won't replace an entry you've already beaten — that's not a bug.
• Give it a moment. Submission isn't instant — the game checks for unsubmitted bests every ~30 seconds, and Steam takes a little while to reflect new entries. If a run still hasn't appeared after a restart, hop into our Discord and we'll take a look.
