Mune or Immune is released on itch.io today, as a submission to the Bullet Hell Jam. There, you play as a virus and you have to avoid the antibodies released by white blood cells. Every 10 seconds, you also get a chance to choose a card to power up (or sometimes down) yourself, but unfortunately, the WBCs too. Nonetheless, it is an epic action packed simple game.
