It looks like God
What is the first thing everyone notice's when playing this game? The graphics. Wow. I'm gonna say it; these are THE best graphics in a flash game I have ever seen. Ok, ok, the gameplay isn't the MOST riveting thing ever, but what we have for now; I'll take it!
I also really love the physics. They feel smooth and natural, it makes the sperm hard to control, but in a good way if that makes any sense. In fact, I think the art and animation style has a lot to do with the feel and accessibility of the controls. Many games are like this.
"Sure, the graphics are good, but does that make the gameplay any better?!"
Yes, yes it does. Mr. BarfQuestion, this is the best thing you've been involved in since It's Me, Not you. I'm totally looking forward to when you make another game.
...oh wait, you already have. =D
