Testing round #1 — v1.1.9-preview (NPC, events, combat, performance)

First testing round for the **[v1.1.9-preview release](https://github.com/arn-c0de/ZombieEscape-Preview/releases/tag/v1.1.9-preview)**. This issue collects tester feedback for this build. Please comment with your device model, Android version, and what you saw.

### What to keep in mind
The **build/systems layer is v1** — it is still fairly basic and will keep growing over time. Rough edges and placeholder behaviour are expected; the goal here is a baseline, not a finished game.

### Focus areas for this round

**🧟 NPC behaviour** — already has a solid baseline. Watch for:
- NPCs getting stuck, pathing oddly, or clumping
- reactions that feel wrong for the situation (too passive / too aggressive)
- anything that breaks immersion

**🎬 Events** — early stage. Note:
- events that trigger too often / too rarely or at odd times
- events with unclear outcomes or missing feedback
- ideas for new events that would fit

**⚔️ Combat** — collecting improvement ideas:
- pacing, damage/health feel, hit feedback
- what feels unfair or unsatisfying
- concrete suggestions welcome

**⚡ Performance** — important for this build:
- frame drops / stutter (where, and what was happening)
- battery drain and device heat
- load times, memory pressure, crashes (attach details)

### How to report
Comment below with: device + Android version, focus area, what happened, and (for crashes) steps to reproduce. Screenshots/recordings help.

Start with the v1.1.9-preview release and test the listed NPC, events, combat, and performance focus areas on an Android device. Done means reporting the device model, Android version, focus area, observed behavior, reproduction steps for crashes, and any useful screenshots or recordings.
