use the arrow keys to make the cat move. this project is not finished, so I already know it isn't amazing at all. I'll allow comments once it is finished.
this project was kind of tricky, and I used a variable, yvel or y velocity, to make jumping possible. let's just say that the landing is the tricky part. I did look at other platformer projects' coding to make this, so If you've made a platformer before December 6, 2014 then I give some credit to you.
