Bug: Collecting a KEY fails to unlock LOCKED doors globally, as the unlock logic only checks the player's current tile, where no LOCKED doors exist.
Severity: CRITICAL | Confidence: High

🔍 Detailed Analysis

The game's key collection logic incorrectly attempts to unlock LOCKED tiles only at the player's current position (tx, ty) using getTile(tx,ty). Since KEY and LOCKED tiles are always at different coordinates, the t.forEach(s=>{if(s.type===LOCKED)...}) loop never finds any LOCKED sprites. This prevents LOCKED tiles from transforming into EXIT tiles, making game progression impossible after collecting a key.

💡 Suggested Fix

Replace the current single-tile unlock logic with a global search and conversion for LOCKED tiles: getAll(LOCKED).forEach(s=>{addSprite(s.x,s.y,EXIT);s.remove();});

Potential issue: The game's key collection logic incorrectly attempts to unlock `LOCKED`
tiles only at the player's current position (`tx`, `ty`) using `getTile(tx,ty)`. Since
`KEY` and `LOCKED` tiles are always at different coordinates, the
`t.forEach(s=>{if(s.type===LOCKED)...})` loop never finds any `LOCKED` sprites. This
prevents `LOCKED` tiles from transforming into `EXIT` tiles, making game progression
impossible after collecting a key.
