Egg Adventure is a drawing logic-puzzle game. In a world made of blue graph paper and contrasting hand-drawn artwork, the player helps Mr. Egg, an anthropomorphic white egg with short black arms and legs, complete tasks by drawing continuous line platforms, protective barriers and other objects.
The player initially helps Mr. Egg reach a door to the next level. As they progress through the game, the challenges increase in size and scope. For example, the player might need to protect Mr. Egg from toilet plunger projectiles, direct Mr. Egg safely around a trap of pointy spikes, or even lead Mr. Egg in a clear toy bubble ball to roll toward new love. In each scenario, the action must occur within five seconds, or they must try again.
Egg Adventure provides the player with several useful tools and fun extras. The player can reload a level at any time for free using the button marked with a semi-circular arrow near the upper-left corner. If they agree to watch ads, they can receive tips or skip difficult levels with buttons near the lower-right corner.
In the lower-left corner, the player can use the Dress Up button to give Mr. Egg a makeover with a new hat or other clothes. They can also select a toy ball, or gacha, that has unique features. They can use the Brush button marked with a pencil to change the drawing tool. The player must reach a specific level or watch ads to unlock these options. The game also rewards the player now and then with gifts.
