Quick answer: Decouple step gating from animation timing, queue completed actions, and let a fast player's early input still count toward the right step.
Speedy players who already know the controls often break tutorials by doing the next thing before the prompt finishes. The step that was supposed to set up the next one never ran, so an input gets eaten or the flow stalls. Make steps order-robust.
How to fix it
1. Do not gate on animation length
Advance steps on actual completion events, not on a prompt fade or a fixed delay. A fast player should be able to satisfy a step the instant it is valid.
2. Queue early actions
If the player performs the next step's action before its step activates, record it and credit it when the step starts, instead of discarding the early input.
3. Run setup synchronously at step start
Apply a step's required setup immediately when it activates, before any animation, so a fast player cannot act in a window where setup has not run yet.
Catching the ones you can't reproduce
The hardest version of this to fix is the one you can't reproduce — it only happens on a player's hardware, OS, driver, or save state, under conditions that simply aren't present on your machine. A report that says “it crashed” or “it froze” gives you nothing to act on, so the bug survives release after release while quietly costing you players.
Automatic error capture closes that gap. Each failure arrives with its full stack trace, the device and OS, the build number, and a breadcrumb trail of what the player did right before it broke, so even a failure you have never seen becomes a specific, reproducible issue. Fold identical failures into one signature ranked by how many players each hits, and your worklist sorts itself worst-first instead of arriving as a stream of vague complaints.
This is where a tool like Bugnet earns its place. Its SDK captures every Godot error automatically with the full stack trace plus device, OS, memory, build, and game-state context, folds duplicates into one grouped issue with an occurrence count, and ties each to the build it first appeared on — so you fix the problem that hurts the most players first and confirm it is gone when its signature disappears from the next release.
Ship the fix, watch the signature disappear from the next build. That's how you know it's really gone.
