Should I delete the old project before trying again?

Not as a default step. Preserve the existing work and its identifying details, and use only recovery or copy controls you have verified in the actual interface. A new brief does not require destroying the only prior result.

Plan and test game mechanics

A mechanic needs an observable rule: an action, a change in state and feedback to the player. Before adding more systems, test whether the first action, win condition and restart work together. The existing guides below provide the starting workflow and debugging checks.

Prepare a game for publishing

Publishing starts with a game that can be tested, understood and maintained. Check the available creator controls, audience settings and safety requirements before a release. Use the publishing guide for the sequence, and the troubleshooting guide for an actual blocked step.

When to Restart a Roblox Build Project

Restart a prototype only after identifying what the current version gets wrong and what a restart would discard. Prefer a narrow repair when the core interaction is sound; reconsider the brief when the generated loop is fundamentally different from the intended game.

Objective

Choose repair, rescope or restart with an explicit reason and loss inventory.

Before you start

Describe the observed mismatch without assuming its internal cause.
Identify which parts of the current result remain useful.
Keep the original brief and relevant project details available.

Steps

Classify the problem as a local defect, an unclear brief or an inaccessible project.
List work that would be lost or need reconstruction after restarting.
Identify a bounded repair if the core loop is already coherent.
If rescoping is necessary, write the different hypothesis that the new brief will test.
Preserve the old result where the verified workflow permits it.
Compare the next attempt with the new brief rather than judging only whether it looks different.

Verification

The decision names a specific problem that restarting is intended to solve.
Useful work and observations have not been discarded without consideration.
A new brief changes the relevant ambiguity instead of repeating it.
An access failure is not misclassified as evidence that the game design is irreparable.

Limitations

The decision examples are editorial scenarios, not observed recovery outcomes.
A restart does not guarantee a better generation or restore missing work.
Account, billing and moderation problems require their own documented support paths.

Working notes

Separate a defective behavior from a mismatched concept. A stale checkpoint in an otherwise coherent route is a bounded repair candidate. A brief that produced a trading system when you intended a short delivery challenge may require a new scope statement before further edits are useful.

Create a loss inventory before starting over. List working interactions, useful layout decisions, wording, prompts and observations that you want to preserve. Do not delete the only existing project merely to obtain a clean starting point; first understand which copies or recovery controls the current interface actually provides.

Look for a reason the next attempt should differ. A smaller action-and-outcome brief, a clearer reset rule or the removal of conflicting requirements supplies such a reason. Resending the same vague request without a changed hypothesis is not a reliable recovery strategy.

Retain uncertainty when the cause is unknown. If the project cannot be opened, that is an access or loading problem rather than evidence that its design needs replacement. Preserve the project identity and visible error before following the appropriate troubleshooting path.

Examples

Repair decision: movement, pickup and delivery work, but Retry leaves the parcel carried. Keep the version and request a reset-state repair. The working loop provides a useful baseline that a restart would discard.
Rescope decision: the requested city economy has many unfinished systems and no independently testable first interaction. Save the useful setting notes, then write a courier-route brief with an explicit objective and retry boundary before creating another prototype.
Decision record: Current mismatch—no clear terminal state. Preserve—route layout and readable destination. Next approach—request completion and retry behavior before adding progression. Restart is deferred until this bounded repair has a recorded result.
