Awessome game!

This is the simplest and most challenging games I've played thus far! Keep up the good work and i look forward to seein more from u.

Not too bad

Interesting take on the shooter. I wouldn't mind seeing more along this vein. One suggestion though:

Pick darker colors that contrast with the background better. I got some black bullets that I couldn't see, and didn't realize were being ineffective until I forced myself to look at my weapons. Being able to see everything that's happening on the battlefield would be a huge help.

A guy with long arms...

shooting at sperm...
I like the concept but needs work, the pixel art is fine but, the enemies could use some variation and upgrades would be nice.
Oh and a menu screen.
