The player can unlock additional characters by earning points in the most current level of Leap Day. All characters differ in physical appearance and have no distinct behaviours. They all have total of three unlockable selfie poses.
Each character moves left to right, turning back when they hit a wall. The player can make their character jump by tapping on the screen. Characters can make one additional jump while in the air, in which they curl into a spinning ball. The double jump count is reset upon leaving any surface. This includes touching the ground or wall, jumping on an enemy, bouncing off a spring or getting a boost from a jump bubble. It also resets when going through a teleporter.
When characters come in contact with a wall, they grab onto it and slide down until they jump away from it or interact with something else. If the player does not jump when sliding down a wall, the character falls back to the ground directly below or starts walking in the other direction if the wall meets the ground.
The playable characters are vulnerable to all hazards and enemies and die immediately upon direct contact with most of them from the side. Some enemies can be killed by jumping on top of their heads, which rebound the character upwards. Upon death, a character is respawned at the last checkpoint the player activated.
In general, all characters have a round head with two white eyes and a mouth, a body, and two stubby legs and arms.

- The character La Beef is a pun on the name of American actor and director Shia LaBeouf.
- Solder_26 is a reference to the character Soldier: 76 from the video game Overwatch.
- In the May 19th, 2016 preview for Leap Day, which showed the in-game sprites for the characters that would be added in Update 1, four sprites differ slightly from their final versions: La Beef's head is closer to his body, Grill's skin is much lighter, Scalp's sprite has lighter skin, and the bottom part of Kepi's hat is green instead of grey.
- La Beef, Solder_26, Zweiclops, and Rasbunny are the only characters to break the unlock trend of having three selfies unlocked before the next character, as these three characters are unlocked after two selfies are unlocked.
- Zweiclops' name is a pun on Cyclops. "Zwei" means "Two" in German.
- Whip is a reference to the Bad Ice-Cream series.
