Negative Noir

In dualistic world, how long could you survive for?

The rules are pretty black and white. Shoot the right squares with the right colour circles.
The longer you survive for the quicker the enemies will spawn.
So I'll ask you again, how long could you survive for?

Next Update will bring forth a leaderboard and achievements. Game mode will be split into Normal, Hard, Rounds (where you'll defeat enemies in rounds with a 10 second cool off period) and oppostite (the opposite colour will defeat the opposite-coloured enemy).
