I absolutely love the writing and how it's all presented. Actually this is very close to an earlier concept I had before I settled on my idea, our games are almost creepily similar, mostly seperated by the way we implemented "drawing", but we both certainly had some use of ImageTexture. Your game just got a more fun story (and more of it!).
I was gonna send the character I made, but I forgot to take a screenshot (facepalm), so here's a speed drawn version of it (I promise the real one was much better)
