Select a scene from the menu and after it's done scanning look around by dragging your mouse. Press space to open settings. To render at a higher resolution with decent fps copy this project's link into: https://turbowarp.org/
The images are just random ones i found on google plus a couple I made by using my extremely limited blender skills. If you want to add your own panoramic images simply add them as a new costume in the "scenes" sprite. The images should be centered on the canvas and be 480 x 240. Also the image scanner was made by following griffpatch's tutorial on youtube.
