Office Hours #72 · 30 September 2026

Ten prompts.
One trailer.
Zero parking
skills.

An open drop-in with a physics game on screen, and every question answered in between.

Gaming Week drop-in

Questions answered,
one game built.

Wednesday of Gaming Week is an open drop-in. Instead of a blank screen, Sam works on a side project while he answers questions. After seeing a one-prompt game on social media, he rebuilt a 3D trailer-parking simulator in about ten prompts, with a physics engine, a reverse camera, Kenney assets, and AI-designed levels.

During the hour he adds an animated "Let's Park" landing page in which a car reverses into a bay and knocks over cones, then sign-up with a themed login, a pause menu, usernames so no email is ever shown, and a public leaderboard that scores time and damage and rejects impossible numbers server-side.

The Q&A covers account bans, why Base44 apps cannot run offline, the lack of server-side rendering for SEO, PII and security, backend-function and integration costs, app-store publishing, and the Game Jam rules. Sam repeats the central point of the week: the techniques are what matter, not cloning his game.

Patterns from the parking game

Fun, gated,
fair, safe.

  1. 01

    Fun

    A borrowed mechanic plus real physics is enough for a satisfying loop.

  2. 02

    Gated

    Sign-up and save states turn a toy into something people come back to.

  3. 03

    Fair

    Server-side checks stop impossible leaderboard scores.

  4. 04

    Safe

    Usernames, not emails. PII never appears on a public board.

6 lessons

Build it,
then harden it.

  1. 01

    Physics plus assets makes a fun game

    The parking game started with about ten words: an idea borrowed from another game, plus a physics engine. The Kenney asset pack and a reverse camera did the rest. Simple concept, satisfying execution.

  2. 02

    Let the AI design levels

    Sam never designed a level by hand. "Create 10 levels, please" was enough to get a progression.

  3. 03

    Gate the game behind sign-up with saves

    One rambled prompt pivoted the game to a themed landing page, custom-themed sign-up, and per-user save states with Continue your save.

  4. 04

    Never expose emails on a leaderboard

    Give users a username at sign-up so public surfaces never show an email address, which is PII. Make the leaderboard public, injection-resistant, and validated server-side.

  5. 05

    Keep scoring honest

    Paused time should not count. Have the server reject impossible times and damage values so the leaderboard cannot be faked.

  6. 06

    Don't over-polish while building live

    Sam deliberately stops fiddling with a landing animation that runs a little long. Visual tweaks can take up a whole session while nothing new gets built.

Gaming Week,
continued.

As stated on 30 September 2026.

  • Update 01

    Thursday is the live game build

    Thursday's advanced session will continue Meadow Reach, Sam's Settlers clone, and cover APIs, 3D model libraries, and an image-to-Three.js library he has found.

  • Update 02

    How the Game Jam works

    Submit a game to the Launchpad. A screenshot is required. A description and video are optional but earn more votes. Gambling apps, including poker, break the rules.

  • Update 03

    Find every session on Base Camp

    RSVP from the Events tab in Base Camp to get a builder ping and an email when Office Hours goes live.

Several questions were repeated during the session and are merged here. Sam's remark about backend-function costs was a community correction he accepted live; check current pricing documentation.

Bring this to your next build

Park it.
Then ship it.

  1. 01

    Borrow a mechanic, add a physics engine and an asset pack, and you have a fun game in about ten prompts.

  2. 02

    Give every user a username so emails never appear on public surfaces.

  3. 03

    Validate scores server-side and exclude paused time.

  4. 04

    Plan SEO around the current lack of SSR.

  5. 05

    Learn the technique on screen, then build your own idea for the jam.

Keep learning
