As the game is now, the player (a purple square) files through the cave (up and down arrow keys are used for movement), trying to avoid the cave and the enemies (which are yellow squares, I will call them "ghosts" on account of the fact that they can move through solid rock on account of laziness for generating smarter movement), and the player accumulates score as time passes and additional points as enemies go off screen, enemies spawn more frequently as time progresses. The player also has 2 special "weapons": an invisibility/invulnerability cloak activated by pressing '1', and a turbo activated by pressing '2'.
tl;dr: controls are up/down arrow keys for movement, 1 for invisibility cloak, 2 for turbo.

As something that could be called a game exists, I will call this more successful than my last game jam attempt. In the future, the following things may or may nor be implemented/fixed:
-A bug where the player randomly dies from "colliding with the cave" without actually colliding with the cave some times (DONE)
-Somewhat smarter/potentially varied enemies.
-Better enemy spawning speeding up method (DONE)
-Graphics that are slightly more detailed for player/enemies
