Scope
Does it affect startup, every level, one level, the editor, or only online content?
Symptom checklist
Progress in this checklist stays in this tab and is not diagnostic telemetry.
Isolation order
Does it affect startup, every level, one level, the editor, or only online content?
Write down the last action before the failure: load, input, transition, save, exit, or download.
Change one setting or file condition, retest the same scene, and undo changes that do not help.
A useful report includes platform, game version, the exact message, whether it happens in a simple level, and whether third-party modifications are enabled. “It does not work” hides the evidence needed to choose a safe next step.
Before destructive steps
Do not treat reinstalling as the first universal fix. Local-save behavior differs by platform, and cloud data must exist before it can be loaded. Follow the current official account guidance and confirm important progress is preserved.
If a problem begins only with a third-party tool enabled, disable that tool and test the base game first. That separates a modification conflict from a base-game issue without inventing a cause.
Comparison test
A browser game cannot diagnose the installed game, but it can tell you whether pointer or keyboard input and basic browser rendering work in another environment. It does not prove that the official installation is repaired.
Play next
Open a separate browser game to practise related movement. This recommendation does not claim that the exact level in this article is included.

Lag can have several causes. Separate a device-wide problem from one object-heavy level, then test storage and the relevant in-game graphics options one change at a time.
Record when it crashes, protect your save, and consult the current official FAQ. It notes incompatibility, large save files, and object-heavy levels among possible factors.
Check in-game volume and the operating system mixer first. A failure affecting only custom songs may have a different cause from all game audio.
The official FAQ describes screen tearing as a refresh-rate synchronization issue and recommends testing Vertical Sync. Because VSync can affect input delay, compare both symptoms.
The official level FAQ says an active Delete filter can cause this. Set the filter to none and test again before changing unrelated files.
No. It stores no telemetry and cannot inspect the game, device, files, drivers, or account. It is a safe order of checks, not an automated diagnosis.
