Hi! Nice application! You can use LoadImageFromScreen() to get screen data as an Image and LoadTextureFromImage() to get a Texture2D to draw on screen again but this can be very slow...
Nice! Feel free to share your creation on raylib Discord community, there is a #madewithraylib channel for that. Also, you can share your creations in raylib GitHub Discussion: https://github.com/raysan5/raylib/discussions/1326
