How to Stay Alive in FlyOrDie: Water, Oxygen, Poison and Fire

Most deaths in FlyOrDie (now EvoWorld.io) are not one big bite. They come from a bar that ran out, a poison you did not clean off, or a place your creature cannot survive in. The game's own messages explain each of these, and this post collects them in one place. Everything below comes from the English text file and the game code that evoworld.io loads.

Water: the bar that never stops draining

The opening tips on evoworld.io are short: eat green, avoid red, and “Do not forget to drink water.” When the bar gets low the game warns: “Your water level is low! You need to drink water to survive!” Water is also your cure, as the next section shows, so a lake or river is worth knowing in every area you play.

The hell forms are the exception. The Demonic Egg Eater, Demonic Bat and Demonic Imp can swim in lava and quench their thirst there, according to their skill texts.

Oxygen: under water and in space

Oxygen is not about flying high. The game gives two warnings: one tells you to “breathe air”, which happens when you stay under water, and the other appears in outer space: “Leave the space or look for cosmic plants.” Diving forms (the Duck, Pelican and Seagull) can stay under water longer, and the cosmic forms have a skill that makes them lose less oxygen in space. Every other form should keep dives short and leave space quickly.

Damage over time and how to clear it

Status	Caused by	How to clear it
Infected	Biting a Mosquito player (a chance on each bite)	Drink water
Poisoned	Wasp, Hornet or Swamp Monster attacks	Drink water
On fire	Demonic Imp, Dragon or Phoenix	Go into water

All three drain a share of your health every second until you clear them, so the right move is to head for water at once instead of trying to out-fly the damage.

Places that hurt

The game names each area as you enter it: water, swamp, lava, toxic water, outer space, and the “fire of death”. Its list of causes after “You were killed by:” includes lava, dehydration, lack of oxygen, poisoning, fire, infection, the fire of death, toxic water, traps and saws. If an area message appears and you are not one of the forms built for that place, turn back.

There are also safe places. The game says “You are in a safe place” when you reach one, and in the Battle Arena, which only Reapers can enter, you do not lose experience when you die.

Escaping a predator

• Know who hunts you. As a Fly, the hunters in the food table include the Dragonfly, Blue Bird, Red Bird, Blackbird and Brown Bird, plus computer creatures such as frogs.
• Use your form's defence. The Butterfly is invisible to predators while it sits on a flower. The Fly has a 50% chance to dodge an attack. The Pterodactyl blocks the next attack, and the Stone Eater has a 75% chance to block one.
• Break line of sight in cover. The code has a separate object type for hiding places, and the objects in it are clouds, a bright green bush and an igloo. Head for one when something red is behind you.

If you die anyway

The game has revival tokens: each one lets you keep 1,000 experience points when you die. You can buy them in the shop or earn them in the game.
