Petri-Dash is one of the new generation of “dodge everything” games that realizes a game can always use something more to do than just dodge things. In this case you are some sort of sub-species that lives in a Petri dish, and all you want to do is survive. In order to do that you’ll either have to dodge all the other organisms or take them on in a battle of butting heads in order to dominate the dish. Everything comes at a cost, however, and in this case you are constantly losing life just by swimming around. You are also weakened if you collide with another organism without dashing them. When your life is spent is back to the primordial pond for you. You can collect energy pellets to refuel your health, and there are also little versions of yourself that will attach to you when you run them over and give you bonus multipliers to your score. You lose these friends when you hit one of the bad guys.
