Hey, I've been doing scratch for about half a year now,and I am also a big Portal 2 fan. I'm kind of nervous because I'm not sure if I spelled Apeture right(I don't know why I didn't look on google). But here it is! Use arrow keys to move and press the A button once you finish!
I've worked a little bit more on this project and now SAL can move! There isn't much to this still, but it is a work in progress! I'm always open to suggestions, so if there is something that you think I should try, then tell me and I'll try to make it happen!
