Bosses

• Every boss has its own arena now: much wider, and built around its attacks with lava pools, crumbling ice, ledges and corner springs.
• The springs throw you a lot higher, right back up to the top ledges.
• Flying bosses get tired. The Broodmother, the Frost Warden, the Ember Wyrm and The Gloom sink to the floor every few attacks. That's your chance to stomp them.

Darkness

• Glut is now called Darkness and has its own selection screen: choose DIVE and pick your level. Normal is always there.
• Beat The Gloom on your highest Darkness to unlock the next one, up to Darkness 10. Every level adds one rule and pays 20% more wax.

Embers of Power

• You always choose from at most 3 Embers of Power. Bosses no longer add an extra card.
• The altar blessing KEEN EYE is now SECOND LOOK: your first reroll after every level is free.

Also

• 13 new achievements: the two deepest worlds, every boss, your first and all candles, all relics, and Darkness 1, 5 and 10.
• The Daily Dive is gone from the title menu, to keep the focus on the main dive and the Chapel.
