Fight Input Bug: Block Flicker and Attack Delay

Short answer

First watch stamina: an empty bar or attack recovery can make block/attack feel ignored. If right-click visibly flickers while stamina remains, leave the fight, click the game window to restore focus, disable mouse/overlay remapping, try windowed mode, and restart. As of July 31, the cited Steam report has no confirmed one-click fix, so preserve a save and change one input variable at a time.

When to do it: Run these checks as soon as a block releases on its own or an attack remains delayed after the visible recovery, before repeatedly dying or overwriting the pre-fight save.

What you need: A save before the encounter, a working mouse with separate left/right buttons, access to Steam file verification, and permission to close overlays or remapping utilities.

Missable or risky: The support check is not missable, but a boss branch can be. Preserve the pre-fight save before testing restarts or alternate outcomes.

Confirmed details

Endacopia uses left-click attacks, right-click block, mouse movement, and a stamina resource. Holding defense continuously or attacking through recovery can create expected gaps that resemble dropped input.

The launch Steam report specifically describes rapid random unblocking and attack delay after blocking. The thread contains no accepted developer fix, so any guaranteed registry, launch-option, or controller solution would be invented.

Window focus, overlays, mouse software, accessibility click-lock, remote-desktop layers, and an unstable physical switch can independently turn one held input into repeated up/down events.

This page separates documented requirements from route advice. Names, achievement conditions, platform details, and item counts are checked against the linked Steam records; navigation is cross-checked against recorded gameplay. If an update changes a room, prompt, or trigger, use the verification note below before assuming the save is broken.

Step-by-step solution

Step 1 — Reload the fight and perform no attacks. Hold right-click while the stamina bar is full; record whether the guard drops before the bar is depleted.

Step 2 — If it only drops with low stamina, release between enemy attacks and shorten punish strings. If it flickers at full stamina, click the game window once and retest in both full-screen and windowed mode.

Step 3 — Close Steam overlay panels, recording overlays, macro/remapping software, and vendor mouse utilities one at a time. Do not disable security tools or make system-wide changes.

Step 4 — Test the physical button in another application, reconnect the mouse, or try a second mouse. Then restart Endacopia and Steam and verify the game files from Properties > Installed Files.

Step 5 — If the issue persists, keep the pre-fight save and report the build, display mode, mouse model, stamina state, and a short recording in the Steam discussion rather than presenting an unverified workaround as fixed.

Common failures and softlock risks

Do not confuse normal stamina exhaustion with a software bug. A full-bar flicker is the useful diagnostic difference.

Controller support is not advertised on the main Steam system-requirements panel. A community mapping can help on Deck but is not proof that every controller path is supported.

Avoid downloading third-party patches or changing hidden system settings from an unverified comment. The source report currently has no confirmed universal remedy.

Recovery rule: stop before crossing another chapter boundary. Confirm the current objective, cycle every usable inventory item, and retry the interaction from a clean room entry. If the trigger still fails, close the game before restoring a known-good save; copying or replacing live save files while the game is open can overwrite the recovery state.

Version and verification

The symptom wording and lack of an accepted solution were checked directly in the launch Steam thread; the input model and keyboard/mouse requirement were checked against Steam's official game and demo pages.
