I totally feel you on the art style thing and I'm pretty much on the same boat. Like, I would love to make polished, "professional" art, but my skills are far from that level so rather than trying to force "good" art for my personal projects and our games we submit, I instead tailor my art on a per-project basis and use very specific art direction. Basically, I hide my lack of "high quality" artwork behind intentional art direction that complements the mood and theme of the project (the "essence" of it, if you will). I've embraced this sort of philosophy as of late because I've come to realize that drawing is not fun when your main priority is making it "look good" rather than letting it complement your project regardless of how "good" or "bad" it looks (art is subjective after all). In my opinion, it's fun to work within your limitations and that's what makes the learning process interesting and engaging.
It's cool reading your comment feels like wr are at tg same place in our journey - putting creativity and fun first.
Wishing you the best on your creative journey. I honestly was really impressed and loved your innovative game.
The concept could make a cool utility where you draw a simple line art and colour it in and can save as a gif or something (due to the motion in your game would lose something as a still. I would use it as could make some fun stylized assets for a game or bild ui with it.
