TouhouNuclearOverlay

Adds a Touhou-themed visual overlay when the Apparatus is pulled, replacing the default radiation warning with stylish scrolling caution bars and radiation symbols.

Features

• Scrolling CAUTION bars at top and bottom of screen (with breathing opacity effect)
• Scrolling radiation symbols across the center
• Smooth fade in/out animation (1s fade in → 13s hold → 1s fade out)
• Resolution-independent scaling (works at 1080p, 1440p, 4K, etc.)
• All players see the overlay (not just the player who pulled the Apparatus)
• Renders above FacilityMeltdown's UI (sortingOrder 10000)
• No external dependencies beyond BepInEx

Recommended Companion Mods

• TouhouMeltdownBGM — Replaces meltdown music with Touhou Nuclear Fusion theme
• FacilityMeltdown — Adds the meltdown mechanic (this mod enhances its visuals)

Installation

1. Install via r2modman/Thunderstore, or manually place plugins/TouhouNuclearOverlay.dll in your BepInEx plugins folder
2. Launch the game — overlay triggers automatically when Apparatus is pulled
