Enemies in Leap Day harm the player characters on contact, sending them back to their most recently activated checkpoint. Most enemies can be killed by jumping on their heads, but they will all respawn if the player dies and restarts from a checkpoint. They also will respawn at the exact place they start the movement. Most of them follow a set pattern, moving from left to right like the player.

On Leap Day's initial launch, the game had a set of enemies that could appear in any of the themes. Later additions are exclusive to one or two themes.

LeapDay YolkStanding     Leap Day Valentines Archer
First appearance February 14, 2017
Movement

Flies in the air horizontally and/or vertically, but can also be stationary

Contact
  • Deadly from the sides and bottom
  • Can be bounced on from the top (except when arrow is aimed upwards)
Behaviour When the player's character is in view of an archer, with no platforms or walls obstructing it, the archer pauses its movement to draw its bow and arrow. It will aim for a brief moment before shooting the arrow towards the player's current position at the time of shooting. This arrow can kill the player's character if it makes contact.

If the player's character passes an obstacle that blocks an archer's view of the character while it is aiming, it will stop aiming and resume its movement. The arrow is only launched when the character remains in the archer's view parameter for a while and can be avoided if the player's character is moving and not turning at a wall.

Trivia

LeapDay beta mr spring

The early version of spring heads and spike heads.

  • In the March 30th, 2015 preview for Leap Day, early versions of three enemies are seen:
    • Spring heads and spike heads have a slightly different colour pattern and design. The spike head also has a bigger spike and the spring head has a taller spring than with the final version.
    • The small blob was from an early idea where the regular sized blob when jumped on would split into tinier blobs[3]. This feature is now seen in the Toxic Sewer levels.
  • Some enemies can be seen in the audience at the start of each level.
