# VNGame — Iron Hollow PoC

## Run
Open in Ren'Py launcher → Run.

## What to test
1. Play straight through (no checkpoint) — see all 3 base branches.
2. Create a checkpoint → pick "To find something worth doing" → **Rewind**.
   Watch the teal wash and Luno's linger beat afterward.
3. Explore 3+ branches, then the 4th unlocked option appears.

## Missing assets (Ren'Py will warn but not crash)
- `game/images/bg training_yard.png`
- `game/images/sara neutral.png`, `sara pained.png`
- `game/images/luno curious.png`, `luno amused.png`, `luno neutral.png`,
  `luno soft.png`, `luno tilted.png`, `luno still.png`, `luno laugh.png`,
  `luno sharp.png`, `luno linger.png`

Any placeholder PNG renamed to match works fine for testing.
