Vein Dweller

This mod provides a customizable gameplay experience that forces players to remain underground after a certain time period expires. With default settings, the mechanics function as follows:

• When joining a server or creating a world for the first time, players receive a 2-minute grace period to gather surface resources before descending
• After the timer ends, players must stay below sea level (y=64) and avoid underground areas with direct sky exposure
• Remaining in surface danger zones inflicts damage of one and a half hearts per second
• During nighttime, surface damage is disabled, or the timer pauses until morning arrives

The mod supports server compatibility - installation is required on both client and server.

Customizable Settings

• Initial Countdown - starting time for each player upon first login
• Danger Height - altitude level below which players must remain
• Damage Frequency - interval between surface damage instances
• Damage Intensity - amount of damage received
• Damage Type - type of inflicted damage (void, fire, lava, drowning, suffocation, or starvation)
• Daytime Countdown - timer pause during nighttime hours
• Sky Visibility Damage - automatic damage regardless of altitude when sky is visible
