The loop, in the order the game runs it
Fly out, steal, carry, place, hatch, earn. The developer's own description states the same order and adds that your flight speed grows as you progress, that farther areas hold better Eggs, that rarer Animals earn more Cash, and that Animals keep earning while you are offline. The two steps that are easiest to get wrong are the middle ones: an egg is not yours until it reaches your own ground, and an Animal earns nothing until you place it.
Stealing an egg: what the game asks you to press
Stand at the egg on a nest island and press E when the prompt appears; the prompt itself reads open-now in the client's own language. The egg is then carried rather than banked, and the carry controls offer a drop button - Soltar in the Spanish client - plus a teleport back to your base. The game asks for your own ground before the egg can be placed. A guardian can interrupt the steal, and the HUD carries a separate Jail Guards for 15s control that the recorded sessions used instead of being chased; what that control does to a guardian was not observed.
From a carried egg to your first Cash
Back on your own ground, drop the egg and place it anywhere. A countdown runs on the placed egg; the ones that could be read were a Hen Egg at 0:01, a Rooster Egg at 0:04, a Mystic Ladybug Egg at 0:36 and a Poison Ant Egg at 4:56, and the egg prompt offers an open-now option that skips the rest of the wait. The Animal that comes out is what earns: place it and read the Cash-per-second figure next to its name, because that printed figure is the only income value this game publishes.
The two free things and the first paid one
Two grants arrive before you have to decide anything: a session received Speed 20 to 21 and Wing Stamina 10 to 12 as free toasts, and the upgrade stand advertises free Wing Stamina. The other free reward is the group Animal, claimed by liking the experience and joining the developer's group. Your first paid decision is then a choice between a wing card, a Speed card, a Wing Stamina card and a Carry Limit card: the cards that were read priced Wing Stamina 12 to 14 at $9k or 9 Robux, Carry Limit 1 to 2 at $500k or 99 Robux and Speed 21 to 22 at $263 or 3 Robux.
What each system is for, and when it matters
Wing Stamina buys distance and is the only one of the three that can end a crossing on its own, so it matters the moment a flight falls short. Speed buys time: it changes how long the trip takes, not whether it succeeds, and in the recorded session it was also the cheapest step at $263. Carry Limit buys throughput: it starts at 1 and turns a second egg into a free ride instead of a second trip, and it was the most expensive early step read at $500k. Wing cards are the fourth purchase and are not the same thing as any of them: a wing card states a Wing Stamina multiplier, and the card that could be read completely showed 2.2x Wing Stamina at $100T or 400 Robux.
