Dr. Blob's Organism has a fairly unique approach to the classic arena shooter formula. Your goal is to contain the cellular organisms which are trying to escape the petri dish. Controls are completely mouse based.. and for once, that's not a bad thing.
From the site:"Each level in the game introduces new powerups (like freeze, lightning and multiguns) and special organism abilities (like force field, regeneration and frenzy) to enhance the fun and increase the challenge throughout the entire game."
Dr. Blob's Organism features: "20 levels of increasing difficulty, 10 different power-up's, 5 special blob abilities, 3 difficulty settings, 21 music tracks, Squishy, moist sound effects, Bonus dishes, Jukebox (Play music selections from the game.)"
