Operation "Operation" is a side-scrolling shooter in an early stage of development. While it's not very impressive yet, we are planning to expand it much more in the future, after the Lisp Game Jam 2019, for which this game was initially created.

Gameplay

The player can be controlled by either WASD or arrow keys. Space makes the player jump, although this does not do much yet, down or S makes the player crouch, ENTER makes the player shoot.  [I] near the player's health means "invincible".

The player has 100 HP,  so do the enemies. They will come from the sides of the screen and shoot you if they get close enough.  Escape closes the game.
