Dr Blob's Organism is a shooter with a twist. Instead of controlling a spaceship on a screen, you control lasers around a petri dish and fire inward trying to prevent a blob from escaping the petri dish. It's initially quite fun but the novelty of shooting in a petri dish wears off there really isn't enough variety in powerups, graphics or enemies to push you to play. There are freeware games with more varied gameplay.
A smooth shooter but it feels below average in some way. Recommended to try out for the funky music and novel gameplay but thankfully you no longer have to pay for it.
