I am on level 115 at the moment. The game is fun, until you buy your third gravity gun (gravygun)
This is due to the fact that if you place three gravyguns pointing down at about 30 degrees from the horizontal, nothing normal can touch you. Currently i am grinding 112 for money, it gives about 5 million DNA per round, and i don't even have to watch.
Also, once your DNA total goes into 8 digits, your screen layout goes nuts and you start having issues seeing the total, so not sure if i have 50 or 500 million DNA at the moment
Fun little game at first, cool graphics, but utterly broken
