Bacillus, quite small at first, moves along the playing field and can walk through walls. You can control the bacillus by using the arrows on the keyboard or by touching the screen where you want it to go. When the bacilla approaches the letter D, it consumes it and becomes longer. The more letters it consumes, the longer it gets.

Use arrow keys to move the tiles around the playing field. When two tiles with the same office position touch, they combine. Goal of the game: Get the position of the Minister of Health.
