Animal Rivals VR Mod Menu

I need a custom in-game mod menu for Animal Rivals. I play the VR version but launch it through Steam Link on my PC, so the solution has to hook into the standard Steam build and still display comfortably inside the VR headset.

Core features I want to toggle on and off:
• Unlock all levels from the start
• Infinite ammo with noticeably faster shooting

The menu must be reachable in both single-player and multiplayer sessions without causing desyncs or crashes for other players. A button combination on the VR controllers (or a keyboard shortcut that carries over through Steam Link) to open/close the menu would be ideal.

Deliverables
• The compiled mod / injector ready to drop into the game folder
• Any supporting files or configuration needed for Steam Link + VR compatibility
• A concise installation and usage guide

Please keep the implementation lightweight and stable, and let me know if you need additional game files or testing on my side.
