Quick answer: Add an adjustable timing-leniency setting that widens parry, dodge, and rhythm windows, with generous presets for players who need them.
Frame-perfect timing locks out players who need a wider window. Adjustable leniency fixes it. Here is how.
How to fix it
1. Expose a leniency setting
Add a timing-assist option that multiplies the size of input windows for parries, dodges, and beats, with several levels up to very generous.
2. Add input buffering
Buffer inputs slightly before and after the window so a press that is a little early or late still counts, smoothing out execution.
3. Keep feedback honest
Still show whether a hit was early, late, or perfect so players can improve, while the leniency setting ensures they can succeed in the meantime.
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 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.
The bug you can't reproduce isn't gone — it's just invisible until you capture it from the player's device.
