Thank you for your praise! I didn't spend much time on the thumbnail image or textures, because getting a minimal playable game with a few levels, was my priority. But you're right, it's not a very attractive image, and I wasn't very happy with it when I made it. I considered using an AI generated image but I don't really like to do that. Next time, i'll give it some more thought. Or find someone to join me who can do graphics better than I can.
