Those who make art themselves do it after real hours of hard work with passion. For my 3D game in this game jam, I created most of the 3D models, especially two robots and machines, animation etc. myself in Blender after working for several hours as I am a light user of Blender. It took more time than setting the scene and event sheet in GDevelop. A couple of months ago, this would have taken a couple of weeks to make 3D models in Blender. So I understand the pain and passion of an artist who makes art by themselves in 2D and 3D. On the other hand, for the YouTube Playables Challenge, I only generated the background picture for my 2D game from gemini.com. I did not crop the picture, though I could do it easily as the "AI mark" is at the bottom right side of the image in the case of gemini.com. All the best.
