Fun little game. The artwork is well done, and the sounds were alright. I don't think the music was the best fit, but it suited well enough.
Not sure if it was intended, but if you line up two nogs you can score both with one click. The clicking seemed a tiny bit slow, but then again I may have just been missing once or twice with my frantic mouse work.
Given that it's only 45 seconds, the cactii should start right at the beginning for more of a challenge.
@Alex-Haw Most of the games on Newgrounds involve repetitvely clicking moving objects, so this seems to fit in well. Actully, there are pleanty of point-and-click escape games, which involve repetitvely clicking on NON-moving objects. This game is so advanced!
