Yeah... I needed to make this for a bio presentation. Q and P control the atria and Z and M control the ventricles. As usual, run in turbo speed. I guess I have to apologize for quitting without telling you guys. I got really busy with high school and didn't get the chance to sit down and actually say good bye. Also, I was hoping for Scratch 2.0 to be much faster so I can actually make a game with the raycaster, but that didn't work out. Well, I'm now learning how to program in C so that's where I'm headed... I'll be using scratch here and there but nothing major like before... Also, I got a deviantART account for those interested. My username is swordofevilbane . Come check it out if you're curious to see my works! :)
