Stage Unlock & Enemy Spawn Update

🗺️ Stage Unlock System

A new stage unlock system has been added.

Reach a new stage during a run to permanently unlock it as a starting point for future runs.

Starting from a later stage grants reward boxes to help you prepare:

• Stage 2: 7 reward boxes of each type

• Stage 3: 14 reward boxes of each type

👹 Enemy Spawn Improvements

Enemy spawn flow has been improved to reduce downtime between encounters.

• If all enemies are defeated before the next scheduled spawn, the next enemy group will spawn immediately.

• Reduced the enemy spawn warning duration, allowing enemies to appear sooner.

• Added minimap warning icons for incoming enemy spawns.
