Add juice: hit-flash, trauma-based camera shake, and audio ducking wired so one hit fires all three — for games that feel flat or lack impact.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Game Feel — The Trio That Makes Hits Land

Particles do not make a game feel good. Screen shake alone does not either.
What makes a hit land is three systems firing on the same frame: a sub-frame
**hit flash** on the body that got hit, **trauma-based camera shake** with
quadratic falloff so big hits saturate, and **audio ducking** that briefly
squashes Music/Ambient so the impact SFX punches through. This skill installs
the canonical Summer Engine stack as three small systems wired to one signal.

## Step 1 — Ask what feels flat

Open with one focused question. Wait for the answer.

> What feels flat? Pick one to start: combat hits / pickups / explosions / spell casts / something else.

If the user says "all of it", anchor on **combat hits** — the hit-flash + shake + duck trio is the loudest perceived improvement per minute, and pickups/explosions reuse the same building blocks afterwards.

## Step 2 — Read the current scene state

Before adding anything, see what's there.

**Preferred (Summer MCP):**

```
summer_get_scene_tree
summer_inspect_node "./World/Enemy"   # the body that gets hit
summer_inspect_node "./World/Player/Camera3D"   # the camera to shake
```
…

How to install

The exact contents, by fingerprint

mdr add summerengine/summer/game-feel@sha256:0a7620604e6a48d9

The line at the top of this page pins the label git:20261010.4ade947, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
