Remember that frost overlay for Powdered Snow? Pretty cool, huh? My thought process with this mod was essentially just taking the idea to its logical extreme. 'Ominous Overlays' adds screen changes for all sorts of different conditions, including potions, damage, hunger, oxygen, and the like. This mod is mostly just client side, and is intended to offer a bit of consistency, as well as just some cool new (and occasionally helpful) overlays to the game.

• The Damage Overlay appears whenever the player takes damage greater than 1.5 hearts. It's a red, spikey overlay that has a different direction depending on where the attacker is relative to the player. (Above, behind, in front of, or to the right or left.) If too much damage is taken at once, the screen also takes on a red hue with increasing duration based on the amount of damage taken.
• If the player is low on health, the Heartbeat Overlay appears. It looks similar to the damage overlay, but pulses on and off with increasing speed the lower the player's health is. It's accompanied by a heartbeat sound effect to further implore the player to do something about it.

• The Hunger Overlay pulses a pale white around the edges of the screen, with increasing speed and intensity the lower the player is on food.
• The Oxygen Overlay subtly blacks out the edges of the player's screen when their oxygen bar is depleted. When the player is fully out of oxygen, their screen rapidly begins to pulse black.
• Each Potion now has a unique overlay. For potions where remaining time is important, (Night Vision, Invisibility, Water Breathing, etc;) the potion overlay flashes quicker the less time is left of the potion effect. Other potions, such as Strength, Speed, Regeneration, etc; flash when their effect is in use. (When the player is attacking, running, or healing, respectively.)
• Gaining EXP triggers the Experience Overlay, in which EXP orbs bubble up around the player's EXP bar. When the player gains a full level, their screen pulses with bubbling orbs.
• A Fire Overlay appears when the player takes damage from magma-rock, campfires, or flames. It pulses with cinders around the edges of the screen.
• The Wither Overlay appears when the player takes damage from Wither Roses, the Wither, and Wither Skeletons. It consists of thorny tendrils that grow rapidly around the player's field of view.
• A Thorns Overlay appears when the player takes damage from Cacti, Sweet Berries, or an enemy with armor enchanted with thorns.
