- Disabled V-Sync for better performance
- Auto-detect native monitor resolution with DPI awareness, resulting in sharper visuals on high-resolution displays
- Full support for keyboard and mouse input
- **Configurable player username/nametag** — edit `username.txt` next to the exe to set your in-game name
- **Persistent game settings** — gamma, music, sound, difficulty, HUD options, debug flags and all other settings now survive restarts (saved to `settings.dat` next to the exe)
- **Correct world save names** — save slots now display the actual world name instead of a raw timestamp; save list is sorted newest-first and refreshes without restarting
## Controls (Keyboard & Mouse)
- **Movement**: `W` `A` `S` `D`
- **Jump / Fly (Up)**: `Space`
- **Sneak / Fly (Down)**: `Shift` (Hold)
- **Toggle Fly**: `F`
- **Sprint**: `Ctrl` (Hold) or Double-tap `W`
- **Inventory**: `E`
- **Drop Item**: `Q`
- **Crafting**: `C`
- **Toggle View (FPS/TPS)**: `F5`
- **Toggle Debug Info**: `F3`
- **Open Debug Overlay**: `F4` (Debug builds only)
- **Fullscreen**: `F11`
- **Pause Menu**: `Esc`
- **Toggle Mouse Capture**: `Left Alt` (for debugging)
- **Attack / Destroy**: `Left Click`
- **Use / Place**: `Right Click`
- **Select Item**: `Mouse Wheel` or keys `1` to `9`
- **Accept Tutorial Hint**: `Enter`
- **Decline Tutorial Hint**: `B`
- **Host Options / Player List**: `Tab`
## Build & Run

```
## Runtime Files
Some features require files placed next to the built executable (`x64\Debug\` or `x64\Release\`):
| File | Purpose |
|------|---------|
| `username.txt` | Plain text file — first line becomes your in-game name and nametag. Created automatically with default value `Windows` on first run if absent. |
| `settings.dat` | Binary save of all game settings. Written automatically whenever you change a setting; loaded on startup. Delete it to reset all settings to defaults. |
## Known Issues
- Builds for other platforms have not been tested and are most likely non-functional
- There are some render bugs in the Release mode build
- Changing the resource pack on an existing world while loading it may crash (`reloadAll` called during world load) — use the default resource pack or select it when creating a new world
