Solar Apocalypse

Solar Apocalypse starts on day 20, when exposed blocks begin transforming and water evaporates under daylight. Later phases arrive on days 40, 60, 80, 100, 120 and 140, and each one adds mobs and items that burn in sunlight, a lower height limit above which players burn, and more frequent lightning and thunderstorms. The time is set forward at each phase, so the world skips past the stage it has just cleared.

The phases can be tuned in the config. Blocks affected by the heat layer can be chosen, lava can be turned off for the phases that use it, and the phase schedule can be disabled. Susceptibility to apocalypse fire damage is multiplied, and a heat overlay with fog grows stronger the closer the player stands to the sun. The mod runs on the client and the server together, and it requires Cloth Config API, Fabric API and Fabric Language Kotlin. Day Dream, Daylight Mobs Reborn and Mod Menu are optional; Day Dream lets players sleep during the day, and Daylight Mobs Reborn allows hostile mobs to spawn in daylight.
