Floor Is Lava Mechanics

Lava gradually rises or falls, with a higher likelihood of rising when near the bottom and falling when closer to the top.
Every 600 seconds, the lava makes a significant shift, either up or down, moving up to 50% of its total maximum height.
If the lava is near its maximum height, the countdown to the next "big move" is halved.
Upon spawning, the lava determines its minimum and maximum heights based on the positions of the lowest and highest creatures in the map.
Contact with the lava propels you upward and ignites you.
If you spawn beneath the lava, it pushes you upward until you reach its surface, at which point you catch fire.
