OK, I know it's simple, but me at 10 pm couldn't think about anything other than "MAKE ROOM DESIGN GAME!!!". So, yeah. Click to change costumes, drag to move. About the simplest thing ever. Also, you can change it from the thumbnail, but if you click the green flag it will show you a different design.
Art and code by me. That's all. If anybody wants more costumes or furniture tell me in the comments and I will add them in because I kind of like making these simple designs. Take the sprites if you want. I don't care whatsoever. 4-20-26 shared it! 4-21-26 added new shelf variation!
