Sprites that are underlined in purple are the ones I recommend you use. You can press space/click the little concept box to change it, but that box ain't that important. Press m to switch to thumbnail, because it's probably more high quality than the project itself <:)
For @jacop_marley I know I asked you for details, but I decided I may as well try doing a few concepts anyway :P This is technically a work in progress, but if what I've done so far is good enough for your project, I made a costume to make it easier for you to access the useable sprites. It's in the "Cody" sprite, and the costume's called "USE THESE!!!!" If you want me to make any changes, by all means, do tell me! EDIT: sigh it seems the thumbnail doesn't work outside of the project
