The main point of the game is to avoid the hexagons and reach a score of 50. You get points when you, the circle, avoid a hexagon trying to trap you and it vanishes as it touches the main cortex, an explosive spot of energy. The player always stays in the orbit of the cortex, and it points in the opposite direction of your cursor. For example, if my cursor were at the bottom of the screen, then the player would still be the same distance from the orbit, just at the top of the orbit. Try it for your self!
Some youtube video where a dude made a similar game in 10 min. Don't have a link tho
